palette and event

[Swarnim Ranjitkar]

I was trying to attach AjaxFormComponentUpdatingBehavior to palette and looks 
like I can't do it this way. Is there anyways to attach action to palette 
change event. 
Here is my code. Appreciate you feedback

Palette<DtAddDisplay> affiliatePalette  = new 
Palette<DtAddDisplay>("affiliatePalette",
                new PropertyModel(this.getModel(),"allFilteredDtAdd"), 
                affiliateRenderer, 12, false);
        affiliatePalette.add(new  AjaxFormComponentUpdatingBehavior("onchange") 
{
            protected void onUpdate(AjaxRequestTarget target) {
            
            }
        });
