How to set a handler for markers in Yandex.Maps?

Question

JavaScript

There is a button, by clicking on which a marker is added to the map, you can add any number of them.
I need to be able to do something with it when I change the coordinates of any of the markers (for example, the dragend event ). For example, change its icon.
How to implement so that there is one handler for all markers?

Answer 1

What is the problem or is this a trick question?

dragHandler = function(e) {
// меняем иконку
}
marker.events.add('[drag]', dragHandler);
