CacheElement Event Handler

[an...@axa.com.au]

I'm adding an event handler for a specific cache item like this:
 ElementAttributes attr = 
(ElementAttributes)cache.getElementAttributes().copy();
   if(name.equalsIgnoreCase(EPlatformTask.CONTROL_CACHE_ITEM_NAME))
       attr.addElementEventHandler(new 
com.axa.eplatform.util.ecache.jcache.ControlItemEventHandler());
   attr.setMaxLifeSeconds(ttl);
   cache.put(name, obj, attr);

Here is event handler's code:

package com.axa.eplatform.util.ecache.jcache;

import org.apache.jcs.engine.control.event.behavior.IElementEventHandler;
import org.apache.jcs.engine.control.event.behavior.IElementEvent;
public class ControlItemEventHandler implements IElementEventHandler {

  public java.io.Serializable handleElementEvent(IElementEvent event){
 
System.out.println("\n\n\n\n**********************************************");
    System.out.println(event);
 
System.out.println("**********************************************\n\n\n\n");
    return new String("Test");
  }
}

But this "handleElementEvent" doesnt get invoked.....why????
