[Solved] Cascade DropDownList, how to set JSON variables

[bbeatty]

I have a cascade drop down where I need to set the variable name different than the name of the combo box.
I'm calling an external site and their variable name doesn't match the name of my drop down list.

ex:
@(Html.Telerik().DropDownListFor(m => m.ClaimCategoryId)
                       .Name("ClaimCategoryId")
               .DataBinding(d => d.Ajax().Select(MVC.ClaimCategory.GetAllCombo().GetRouteValueDictionary()))
                .CascadeTo("ClaimCoverageId")
               .ClientEvents(events => events.OnLoad("onAjaxDropDownLoad"))
           )
 @(Html.Telerik().DropDownListFor(m => m.ClaimCoverageId)
                  .Name("ClaimCoverageId")
         .DataBinding(b => b.WebService().Select(webServiceUrl ))
           )

The parameters for webServiceUrl is Id. 
I already have an Id in my model and cannot use this as the name of my drop down.
How do I get the cascade to send "Id" instead of "ClaimCategoryId" ??

I have a similar issue with an internal Controller
