Strange ComboBox issue when returning a view

[Tom]

Environment:

ASP.NET MVC 3 
C#
Razor ViewEngine
Telerik MVC v.2011.2.712.340
 
I'm using the below code to set a combobox (within a form) text via a value when a page is loaded

@(Html.Telerik().ScriptRegistrar().Globalization(true).DefaultGroup(group => group.Combined(true).Compress(true)).OnDocumentReady(@<text>
          //Select EU
        var Ticket_EndUserID = $("#Ticket_EndUserID").val();
        var TicketEU = $('#TicketEU').data('tComboBox');
        var selectEUItem = function (dataEUItem) {
            return dataEUItem.Value == Ticket_EndUserID;
        }
        TicketEU.fill(function () { //binds the combobox
            TicketEU.select(selectEUItem);
        })
</text>))

This work fine. Ths issue is when the form is submitted and I return the view with errors the combobox just has the value in the combobox field instead of the text.

If I comment out the above like below then when I return the view with errors the comobox has the text in instead of the vaule, which is correct. But when the page is loaded the combobox has no vaul/text:

@(Html.Telerik().ScriptRegistrar().Globalization(true).DefaultGroup(group => group.Combined(true).Compress(true)).OnDocumentReady(@<text>

       @* //Select EU
        var Ticket_EndUserID = $("#Ticket_EndUserID").val();

        var TicketEU = $('#TicketEU').data('tComboBox');
        var selectEUItem = function (dataEUItem) {
            return dataEUItem.Value == Ticket_EndUserID;
        }
        TicketEU.fill(function () { //binds the combobox
            TicketEU.select(selectEUItem);
        })*@
        </text>))
