RadAjaxManager Blocks server side event

[RYan]

I have a submit button white pops a radconfirm dialog asking Yes or cancel. If they click Yes then I need to update a textbox from server side c# code. But if I do all of this the RadTextBox ontextchanged method is never fired

Once again, THE PROBLEM IS RADTEXTBOX ONTEXTCHANGED NEVER FIRES!!!!!! HOW TO GET IT TO FIRE THE SERVER SIDE EVENT? I can not remove it from up UpdatedControls because I need it for the confirm dialog

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">

                <AjaxSettings>

                    <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

                        <UpdatedControls>

                            <telerik:AjaxUpdatedControl ControlID="lblError" />

                       <telerik:AjaxUpdatedControl ControlID="txtSONumber" />

                        </UpdatedControls>

                    </telerik:AjaxSetting>

                </AjaxSettings>

            </telerik:RadAjaxManager>

<telerik:RadTextBox ID="txtSONumber" Width="300px" runat="server" AutoPostBack="true" CausesValidation="true"

                                Onkeydown="Keypress_Event()" ontextchanged="txtSONumber_TextChanged" >

                            </telerik:RadTextBox>

function Keypress_Event() {


              var combo = $find("<%= txtCustomerName.ClientID %>");
              combo.set_value("");

          }

Hello,

I tested the provided code and OnTextChanged event is fired as expected. I am attaching my test page to this message for your reference. Give it a try and let me know what is the difference in your case.
