I remember I had a similar issue with this control. Now it works for me with the following Javascript code :

<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.open();
    }
</script>

Hope it helps !

The problem is that, by default, the window will be destroyed (removed from the DOM) on closure. I would suggest removing the "undefined" condition i added in the example below and, instead, dont create the "Details" div in the first place.

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

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

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

        if($("#Details") == undefined)
            $("body").append("<div id=\"Details\"></div>

        $("#Details").data("kendoWindow").refresh({
            url: "/Brand/Edit/" + dataItem.Id
        });
        $("#Details").data("kendoWindow").open();



    }
</script>
