I would like a GameObject to have both a Collider and a Trigger

I have a goal area which I want to be a Collider (working fine) and a Trigger (so I can take some action now another object has entered this area.

I added 2 Polygon Collider 2D components to my GameObject one which is a collider and one which is not. I add a script to the GameObject with the following code:

 public class GoalListener : MonoBehaviour {
 
     void OnTriggerEnter(Collider other){
 
         print ("GOTCHA");
         //Destroy (other.gameObject);
     }
 
     void OnTriggerExit(Collider other){
         
         print ("OH YOU EXITED");
         //Destroy (other.gameObject);
     }
 
     void OnTriggerStay(Collider other){
         
         print ("YOU ARE NOW IN STAY");
         //Destroy (other.gameObject);
     }
 }

But for some reason my OnTriggerEnter, Exit and Stay never fires. The object which enters the trigger has a RigidBody2D and a Circle Collider 2D.
