title: Unity3D IPointerDownHandler on other object
body: <p>I have code like that</p>
  
  <pre><code>using UnityEngine;
  using UnityEngine.UI;
  using UnityEngine.EventSystems;
  public class Area : MonoBehaviour, IPointerDownHandler
  {
      public Image Area;
      public void OnPointerDown(PointerEventData data){ //some code...}
  }
  </code></pre>
  
  <p>If I add the class on the Image it works fine, but I'd like to add class to a gameMaganer object and set the image to public value Area and get OnPointerDown on it.
  Possible?</p>
