Is it a good idea to make use of
org.apache.wicket.util.listener.ListenerCollection ?
See org.apache.wicket.ApplicationListenerCollection for example.
ListenerCollection uses CopyOnWriteArrayList but I don't think this is
a problem here.
The old is 'Unbound', the new is 'Bind'.
I think the new should be 'Bound' because the listener is invoked
after the binding.
