Using this library to do an example in Firefox, I realised that if I want to stop the propagation of an event to the map when I clicked in a marker cluster, I couldn't, so for this reason I have implemented a functionality to pass the event variable in "triggerClusterClick" function to allow this variable arrived to handler event and stop the propagation from click event.
In this way, when I did a click in a marker cluster element, this click won't arrived to map.
