catch jquery event at AjaxEventBehavior

[Lurtz Nazgul]

Hi; 

I used jquery dialog. I can open and close jquery dialog box. I represent 
jquery 
dialog as a panel at wicket side.

My question is how can i catch jquery close event ? 

I tested like below but it doesn't work

        dialogConfirmation.add(new AjaxEventBehavior("close") {
              @Override
              protected void onEvent(AjaxRequestTarget target) {
                  System.out.println(" closed" );
              }
        }) ;

Thanks.
