I've some components which require some client side javascript which require one init call (for all) to be initialized. In fact, this init call uses selectors to get at the components to work one.

My issues is with Ajax. It happens that, during it, some new components required this init call are added.

As such, how could I trigger it only once per Ajax request ?

The pattern I'm targeting is for each component to initialize this way to have a behavior in which something would be added only in Ajax request cycle. For non ajax request cycle, I use jquery to do the init, through:

When trying to reach this goal, I tried to run the init call through an header contributor, but the call is then done before my content is put on the page, making it useless:
public abstract class AbstractEditBehavior extends AbstractBehavior
   public AbstractEditBehavior(final AbstractTextComponent<?> component)
       component.add(new HeaderContributor(new IHeaderContributor()
           public void renderHead(final IHeaderResponse response)
               if ((AjaxRequestTarget.get() != null))
                   response.renderJavascript("jQuery.initEdit();", "ID"
                           + response.hashCode());


thanks in advance
