DataSourceRequest won't model bind

[Einar]

I'm following the Virtualization demo at http://demos.telerik.com/aspnet-mvc/combobox/virtualization and get data back initially, however I notice that my request parameter is not being populated with what's sent to the server. Mainly the Filter property is null even though it's included in the request.

 Controller action: 

public JsonResult GetParentResellers([DataSourceRequest]DataSourceRequest request)
{
    //...
}

The only properties that have a value are PageSize, Page and Take.

I've attached an image of the ajax request that the Combobox sends to the server.

Hello Einar,

I could not replicate the issue locally. Could you review the attached test project and modify if possible in order to demonstrate the issue?
