refresh scheduler error

[david]

I'm using this http://www.telerik.com/forums/custom-advanced-form

 I copied the RadAjaxManager and Loading panel per the post. I have a JS refreshScheduler, I have a code behind ajaxrequest handler

when the advanced form closes the JS refreshScheduler fails: 
0x800a138f - JavaScript runtime error: Unable to get property 'ajaxRequest' of undefined or null reference

on    ajaxManager.ajaxRequest('RebindScheduler');

 

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    if (e.Argument == "RebindScheduler")
    {
        RadScheduler1.Rebind();
    }
}

 

 

    function refreshScheduler() {
        var ajaxManager = $find("RadAjaxManager1");
        ajaxManager.ajaxRequest('RebindScheduler');
    }
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"
    DefaultLoadingPanelID="RadAjaxLoadingPanel1">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadScheduler1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadScheduler1"
                    LoadingPanelID="RadAjaxLoadingPanel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadScheduler1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" Runat="server" Skin="Default">
    Loading...
</telerik:RadAjaxLoadingPanel>

I simplified the refresh JS to this

  function refreshCal(arg) {             $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");     }

and added the missing OnAjaxRequest="RadAjaxManager1_AjaxRequest" to call my code behind and life is good
