Fire the registered autocompletion listeners on the given event.

<p>
Each registered listener is invoked in order of registration. If any listener consumes the
event, then later-registered listeners will not be notified of the event. If any listener
cancels the event, then the suggested text will not be inserted.

@param ev the event
@return true, if no listener cancelled the event
