In my code i have checkbox in header not in td but this help you to find corresponding child grid checkbox to,
<script type="text/javascript">
$(document).ready(function () {
$('#grid12').on("click", ".chkbxq", function (e) {
var $this = $(this);
var selected = $this.is(':checked');
var id = $this.attr('id');
var value = id.replace('checkbox_', '');
var rowIndex = $this.parent().index();
var cellIndex = $this.parent().parent().index();
var grid = $("#grid12").data("kendoGrid");
var datatItem = grid.dataItem(grid.tbody.find('tr:eq(' + cellIndex + ')'));
var childgridid = $('.k-detail-row').find('td.k-detail-cell').find('div.k-grid').attr('id');
var valurchildgrid = childgridid.replace('grid_', '');
var childrowscount = $('div[id*="grid_' + valurchildgrid + '"]').data("kendoGrid").dataSource.total();
var check = $('.k-detail-row').find('td.k-detail-cell').find('div.k-grid').find('table').find('tbody').find('input[id*="checkboxChild_' + value + '"]').each(function () {
if (selected == true) {
$(this).attr('checked', 'checked');
}
else {
$(this).attr('checked', false);
}
});

In Child Grid pass unique-key in each child checkbox. INX is our unique-key.Pass Unique-key like this id='checkboxChild_#=inx#'.
