How to trigger a zone update from a jquery Context Menu event ?

I'm trying to use a context menu (using tapestry5-jquery's 
jquery/ContextMenu mixin) to perform an action, and then I want to 
update the page to reflect the new state.  The first part works just 
fine, but I can't figure out how to get the page updated afterwards. 
While a zone update would be ideal, reloading the page would do in a pinch.

I've reduced the problem down to a simple test page:

---------------------------------
ContextMenuTest.tml

<html t:type="layout" title="Context Menu Test"
       xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd"
       xmlns:p="tapestry:parameter"
       xmlns:j="tapestry-library:jquery">

   <t:zone t:id="testZone">
     The count is ${count}.
     <div t:type="any" t:items="contextMenuItems"
                  t:mixins="jquery/ContextMenu"
                  t:zone="testZone"
                  t:id="uid_contextMenu">
        left-click here
     </div>
   </t:zone>
</html>
---------------------------------

---------------------------------
ContextMenuTest.java

public class ContextMenuTest {

   @Persist @Property int count;

   public List<ContextMenuItem> getContextMenuItems() {
     return Arrays.asList(new ContextMenuItem("Update count", 
"updateCount"));
   }

   @Component private Zone testZone;

   @OnEvent(value="updateCount")
   Object contextMenuAction() {
     count++;
     return testZone.getBody();
   }
}
---------------------------------

Thanks in advance,
Robin

Hello Robin,

This mixin only send a simple Ajax call.
It would make sense to ask for a new parameter that specify a Zone to
update.
