Remove grp.listener

[DGrandes]

Same arguments as for grp.listen:

Code:

function removelistenerfn(addr, fn) {
  var id = Scada.encodeGroupAddress(addr);
  var listeners = objectStore.listeners[ id ] || [];
  $.each(listeners, function(index, listener) {
    if (listener.fn == fn) {
      listeners.splice(index, 1);
    }
  });
}

And what do i have to put in "fn". When I close the widget I need to remove the listener that I´ve created when I open it.

Thanks
