Now we have a empty cluster, so we need to add the properties we want to manage with the cluster. The DataLayerClusterer is an extension of [Map.Data layer of Google Maps API v3](https://developers.google.com/maps/documentation/javascript/reference#Data), so we can add features in the usual way:

newCluster.addGeoJson(featureColl, {

idPropertyName: 'id'

});

newCluster.setMap(scope.map);

newCluster.addGeoJson(featureColl, {

idPropertyName: 'id'

});

newCluster.setMap(scope.map);

The event management could be done out of the library:

var eventHoverIn = scope['newCluster']._dataLayer.addListener('mouseover', function(event) {

// Anything

});

var eventHoverIn = scope['newCluster']._dataLayer.addListener('mouseover', function(event) {

// Anything

});
