MVC Wrapper breaking on second call

[Harper]

I set up a window using the Fluent wrappers like so:
@(Html.Kendo().Window().Name("detailsWindow").Visible(false))

I have a JavaScript function (wired to a grid's custom command  - but I don't think that's relevant) that opens the window and refreshes it based on the grid data:
function popupDetailsWindow(e, a){
     var detailsWindow = $('#detailsWindow').data('kendoWindow');
     var item = this.dataItem($(e.currentTarget).closest("tr"));
     var url = '@Url.Action("Details", "Controller", new { id = "__id__" })';
     var refreshUrl = url.replace('__id__', item.ItemId);
     detailsWindow.refresh(refreshUrl);
     detailsWindow.open();
}

This works fine the first time, then fails on the refresh() call, with an error that 'detailsWindow' is undefined. When I remove the MVC helper code, put in a div with Id "detailsWindow", and call $('detailsWindow').kendoWIndow(); after the document loads, it works fine. Is this a bug in the wrapper code, or am I doing something wrong?

Hello Harper,

It looks like the Window's HTML element does not exist the second time popupDetailsWindow is executed, hence the detailsWindow becomes undefined. Sharing code snippets, live link, or ideally - a runnable sample project where the issue is reproduced would help us pinpoint the exact reason for this behavior and advise you further.
