click event for custom markers

[mg1075]

Thanks for writing this directive.
My question is about adding a click event to custom markers, where the array of markers gets attached to the gl-markers attribute.

A mapbox tutorial shows that they manually add event listeners to custom markers.
https://www.mapbox.com/help/tutorials/building-a-store-locator/#add-new-event-listeners

I am able to do similar inside an angularjs controller using the "element" property of the markers api.

My concerns here are:
(1) Is there a different or recommended way of adding a click event using your plugin? (It seems the answer here is "no").
(2) If I have a function in the angular controller to add an event listener to each marker,
do I have to worry about somehow destroying these event listeners in the angular controller's $destroy event? If yes, then how best to remove the listeners added to the custom markers?

function createElementForDivMarker(m_marker, m_index) {
     var el = document.createElement('div');
    el.id = "marker-" + m_index;
    el.className = 'marker marker-' + m_marker.properties.map_marker_class;  
        el.addEventListener('click', function(e) {
            console.log(m_marker.properties);
        }); 
    return el;
 }
