How to get object id at dragend event in yandex map?

Question

JavaScript

For drawing points I use GeoObjectCollection.
You need to get the object id on the dragend event.

this.myCollection.events.add('dragend', function(e) {
                var object = e.get('target');
                var coords = object.geometry.getCoordinates();
               //var id = ???
}.bind(this));

Either I'm doing something wrong, or it's really impossible to do it) Help plz)
