Error iterating over the elements

[JePedrosa]

Good, after iterating on a layer and activating the onclick I realized that later when I zoom on the map it is as if it were saved somewhere and when clicking on an element, it repeats what I have to do so many times As I zoomed, can anyone help me with this?

My code is as follows:

	capa.PrepareLeafletMarker = function(leafletMarker, data) {
		leafletMarker.setIcon(data.icon);
		leafletMarker.on('click', function(){
			alert("1")
                });
       });
