The onAfterEventRender event is fired by the JavaScript Monthly Calendar after the event element was added to the DOM.
You can use this event to add custom event handlers using addEventListener().
Do not modify the visible content using this event - that would cause performance issues. To modify the event HTML, you can use onBeforeEventRender event.
DayPilot.Month.onAfterEventRender(args)args.e - event object (DayPilot.Event)
args.div - event <div> element (it's the top-level element marked with *_event CSS class)
