Grid with filter and detailtemplate doesn't show first column header

[JAN]

In my project, I use the fluent notation.

Situation:
A grid with filterable mode on "row" and with a detailtemplate, bound to a list of objects.

Problem:
In the head of the grid, there are 2 rows (column titles + filters). The filter row contains only 1 <th> element, instead of 2. 

-------------------------------------------
|                     | [ControleId_Title] |
-------------------------------------------
| [ControleId_Filter] |   -->  ???
-------------------------------------------
| [k-hierarchy-cell]  |         11         |
| [k-hierarchy-cell]  |         12         |
-------------------------------------------

In the JS variant of the grid, it works (see http://jsfiddle.net/Sbb5Z/1715/), but in the fluent notation, it doesn't work.
My attachment contains a standard VS 2013 MVC Solution, with the Kendo scripts added. You just have to download the packages AND paste your Kendo.Mvc.dll in the bin folder of the project.
