It looks like events from newly added controls are captured here using asEventStream with jquery's event delegation.

More about event delegation here: http://api.jquery.com/on/

$('#container').asEventStream('click', '.someclass')

If an element with someclass is ever added as a child of #container, clicks on it will fire events. This is true even if the someclass element is added after the asEventStream call.
