Why Is `data(“kendogrid”)` Undefined?

Question

I'm a starter in kendo.ui, I've written this code to create kendo.ui.grid

@(Html.Kendo().Grid<BrandViewModel>(Model)
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.BrandName);
        columns.Bound(p => p.BrandAbbr);
        columns.Bound(p => p.SrcImage);

        columns.Command(command => command.Custom("Edit").Click("editItem"));

    })

    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("CustomCommand_Read", "Brand"))
        .Model(model => model.Id(p => p.Id))
    )
)

When the user clicks the edit button in grid it will show Edit view in kendo.ui.window and the user can edit data.

@(Html.Kendo().Window().Name("Details")
    .Title("Customer Details")
    .Visible(false)
    .Modal(true)
    .Height(400)
    .Draggable(true)
    .Width(300)
    .Events(events => events.Close("onClose"))
)

<script type="text/x-kendo-template" id="template">
    <div id="details-container">
        <!-- this will be the content of the popup -->
        BrandName: <input type='text' value='#= BrandName #' />
    </div>
</script>


<script type="text/javascript">
    var detailsTemplate = kendo.template($("#template").html());
    var windowObject;

    $(document).ready(function () {
        windowObject = $("#Details").data("kendoWindow");
    });

    function editItem(e) {
        e.preventDefault();

        var dataItem = this.dataItem($(e.currentTarget).closest("tr"));

        windowObject.refresh({
            url: "/Brand/Edit/" + dataItem.Id
        });
        windowObject.center().open();
    }

    function onClose(e) {
        var grid = $("#Grid").data("kendoGrid").dataSource.read();

    }

</script>

but in onClose method $("#Grid").data("kendoGrid") is Undefined, please help me, thanks all

try Window load event
