> OnEventHeaderItem doesn't have effect if it is applied to a component refreshed via AJAX. In short, OnEventHeaderItem is applied before the component is refreshed via AJAX, hence the releated event handler is removed from the target component. 
> We could modify JavaScript function Wicket.Ajax.Call.loadedCallback in order to apply header contributors after the component has been refreshed (see patch).
