checkbox event is not firing with jquery

问题

I have got checkbox row in parent grid and checkbox row in child grid as well in Hierarchy grid mode using kendo UI. the architecture is like this...

I have got four rows in parent grid,in that one column is checkbox and for every parent row i have got one child grid with 4 rows in it and one checkbox column as well...

If i click the checkbox in parent grid row i need to access the checkboxes in child grid column related to this row only and need to set the checked attribute as true for that child grid.....

for that I am accessing the parent grid checkbox like this ..

this is javascript function

  <script type="text/javascript">
    $('.chkbxq').live('click', function (e) {
        alert('1'); // this alert is not firing 
        var checkchildgrid = $('#Gridparent').find(".k-detail-row").find('td.k-detail-cell').find('[type="checkbox‌​"]').is(':checked');
        alert(checkchildgrid);
        if ($(this).is(':checked')) {    
            checkchildgrid.attr('checked', 'checked');
        } else {
            checkchildgrid.attr('checked', false);
        }    
    });        
</script>

and this is hierarchy grid code ....

    @model IEnumerable<Topco.TopMapp.MVC.Models.CostPageSearch>
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>
@using (Html.BeginForm())
{ 
   @(Html.Kendo().Grid<Topco.TopMapp.MVC.Models.CostPageSearch>()
        .Name("Gridparent")
        .Columns(columns =>
        {
            columns.Template(@<text></text>).ClientTemplate("<input id='chqprnt' class= 'chkbxq' type='checkbox'/>").Width(30);
            columns.Bound(e => e.CostPage).Width(100);
            columns.Bound(e => e.Description).Width(100);
            columns.Bound(e => e.VendorName).Width(100);
            columns.Bound(e => e.BillTypeDirect).Width(100);
            columns.Bound(e => e.BillTypeWarehouse).Width(100);
            columns.Bound(e => e.VendorName).Width(100);

        })
        .Sortable()
        .Pageable()
        .Scrollable()
        .ClientDetailTemplateId("client-template")
        .HtmlAttributes(new { style = "height:480px;" })
        .DataSource(dataSource => dataSource
            .Ajax()
            .PageSize(6)
            .Read(read => read.Action("HierarchyBinding_Employees", "CostPageDisplay"))
        )
        .Events(events => events.DataBound("dataBound"))
)
    <script id="client-template" type="text/kendo-tmpl">
         @(Html.Kendo().Grid<Topco.TopMapp.MVC.Models.ItemsDescriptionModel>()
            .Name("grid_#=CostPage#")
            .Columns(columns =>
            {
                columns.Template(@<text></text>).ClientTemplate("<input id='checkbox'  class='chkbx' type='checkbox' />").Width(30);
                columns.Bound(o => o.ItemId).Width(100);
                columns.Bound(o => o.ItemDescription).Width(100);
                columns.Bound(o => o.BrandCode).Width(100);
                columns.Bound(o => o.PackSize).Width(100);
            })
           .DataSource(dataSource => dataSource
               .Ajax()
               .PageSize(5)
               .Read(read => read.Action("HierarchyBinding_Orders", "CostPageDisplay" , new { employeeID = "#=CostPage#" }))
           )
           .Pageable()
           .Sortable()
           .ToClientTemplate()
   )
    </script>
<script>

Try this,

 $('#Gridparent').on("click", ".chkbxq", function (e) {

       var selected = $(this).is(':checked');

        var grid = $("#grid12").data("kendoGrid");


        if (selected == true) {

            var check = $('.k-detail-row').find('td.k-detail-cell').find('div.k-grid').find('table').find('tbody').find('[type="checkbox"]').attr('checked', true);
            var asd = check.is(':checked');
            alert(asd);
        }

        });

Use grid click.

This is how I imagine it should be coded - disclaimer I do not know Kendo at all

If we need to process the checkboxes as you WRITE, we can do

$(function() {
  $('.chkbxq').on('click', function (e) {
    var checked = this.checked;
    $('#Gridparent').find(".k-detail-row").find('td.k-detail-cell').find('[type="checkbox‌​"]').each(function()
      this.checked=checked; // toggle
    });    
  });    
});        

If the content is ajaxed in, you need

$(function() {
  $("#Gridparent").on('click','.chkbxq', function (e) {
    var checked = this.checked;
    $(this).find(".k-detail-row").find('td.k-detail-cell').find('[type="checkbox‌​"]').each(function()
      this.checked=checked; // toggle
    });    
  });    
});        

NOTE .find works all the way down the dom, so perhaps you just want

$(this).find('[type="checkbox‌​"]').each(function()

see following if it helps:

 <script type="text/javascript">

   $('.chkbxq').on('click', function (e) {

    alert('1'); // this alert is not firing 

    var checkchildgrid = $('#Gridparent').find(".k-detail-row").find('td.k-detail-cell').find('[type="checkbox‌​"]').prop('checked');
    alert(checkchildgrid);

    if ($(this).prop('checked')) {    
        checkchildgrid.prop('checked', 'checked');
    } else {
        checkchildgrid.prop('checked', false);
    }    
});        

i hope it helps.
