Does jQuery overwrite event listeners?
===

I've got a bunch divs which each contain a remove link attached with the click event below: 

      var observeRemoveRoom = function
        $('.remove_room').click(function(){     
          $(this).parent().removeClass('active');
        });
      }

Clicking it removes the 'active' class of the parent (the div). I call this observeRemoveRoom function on window load which works fine. 

The thing is, I have another function which adds more of the same divs. Since the 'a.remove_room' links contained within the new divs weren't around on window.load I need to call observeRemoveRoom. 

Am I somehow duplicating the event handlers? Does Jquery overwrite them? If so should I unbind the handlers?
