Kendo UI window will not open a view that has a layout

I am using KendoUI for MVC, trying to open a Kendo-UI-Window that loads its content like this:

.LoadContentFrom("Edit", "CustomerContact")
.Events(events => events.Open("centerWindow"))

When the Edit.cshtml view uses my _DialogLayout.cshtml it will not load. When the Edit.cshtml view has Layout = null the window loads just fine.

The JavaScript error that I am getting when clicking to open the dialog is: Uncaught TypeError: Cannot read property 'open' of undefined

Here is my javascript: .Events(events => events.Open("centerWindow"))

<script>
    $(document).ready(function () {
        $("#btnNewContact")
            .bind("click", function () {
                $("#windowContact").data("kendoWindow").open();
            });
    });

    function centerWindow(e) {
        e.sender.center();
    }
</script>

Why would the error happen when Edit.cshtml is using the _DialogLayout.cshtml view which is a stripped down verison of _Layout.cshtml. It works completely fine when I create a view with no Layout.
