Can't detect OnPointerDown on a nested instantiated prefab

I dynamically create instance of a prefab - called Animal. And in some cases - I dynamically instantiate nested prefab inside the Animal - called Carrot.

Both Animal and Carrot implement IPointerDownHandler and have OnPointerDown methods:

Code (CSharp):

1.  
2. // In Animal.cs ..
3. public void OnPointerDown(PointerEventData data)
4. {
5.     Debug.Log("POINTER DOWN IN ANIMAL !!!" + data);
6. }
7. // In Carrot.cs ..
8. public void OnPointerDown(PointerEventData data)
9. {
10.     Debug.Log("POINTER DOWN IN CARROT !!!" + data);
11. }

However - the one in carrot never gets called. I always get the debug log from the Animal instance.

Any idea why I can't detect the pointer down on both so that I know if the user clicked/tapped the carrot or the animal that holds it?

 

At the end of the day - the listener in the carrot didn't fire at all ... even if I remove the other listener.

So - I ended up with converting the PointerEventData parameter data into a world position and compare it with the transform.position of the Animal - and thus specify whether the user has tapped on the animal or on the carrot.

Dumb ... but working
