Nested UpdatePanel - No event fired

Dock

I've built a portal site successfully (all docks are created dynamically) after following telerik portal site sample. I also cloned Horoscopes.ascx called sampleScopes which is a little bit different from Horoscopes.ascx.

For example, there is a search textbox which user can do search. The dropdown list is inside of an update panel (updatepanel1) and it can be populated dynamically after search. The autopostback for the dropdownlist is turned on.

Ideally, if user selects item from dropdown list, it should update text of a lable in another update panel (updatepanel2). But somehow, it doesn't work. The event from dropdown list doesn't fire. But if I move the sampleScopes from dock and put it into regular asp.net page, the event fires. I guess there is something to do with dock and its lifecycle.
Thanks,

I tried the following code and everything seems to be OK.
ASPX:

    
            <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

If you paste some code I'll try to help you.
