 * Sets an event handler for an {@code Element}. All previous event handlers of this type of event are removed.
 * @param element The element to bind the event handler for
 * @param eventType The event type (e.g. {@code ClickEvent.getType()})
 * @param handler The handler that handler the event
 */

  if (element == null) {
    return;
  }
