The FormItemBuilder exposes an EditorTemplateView method which allows a view to represent the item and provides the entire modal to the view.

As the elements available to forms are limited to those hard coded by Telerik and whilst extension methods can be employed to expand this limitation slightly, the ability to create a context specific view would be ideal

The current implementation looks like this

Html.Kendo().Form<Model>()
    .Items(items =>
    {
        items.AddGroup("Test", 1, 10)
            .Items(i =>
                {
                    i.Add().Field(x => x.Username)
                    i.Add().Field(x => x.Password).EditorTemplateView(Html.Partial("MyView"))
                }
            );
    })

In this example, the entire model is provided into MyView. 

I suggest adding an EditorTemplateFor that uses the lamda expression provided in the Field() method such as

Html.Kendo().Form<Model>()
    .Items(items =>
    {
        items.AddGroup("Test", 1, 10)
            .Items(i =>
                {
                    i.Add().Field(x => x.Username)
                    i.Add().Field(x => x.Password).EditorTemplateViewFor(Html.Partial("MyView"))
                }
            );
    })

I'm using the grid with a Status Bar Template and a button component in the template.

When trying to reference the button using the data() method it returns "undefined".

I've made small changed to the Grid's "selection Aggregates" demo to show the problem:

Sample

In the sample code, when selecting a cell in the top grid, the "T" button should be enabled but the line

returns undefined.
