Why does my trigger only fire one time?

I have a collider on an GameObject which contains a textmesh and a BoxCollider2 around its outside edge, with the is trigger box ticked.

I have a script on the GameObject with the following code:

 using UnityEngine;
 using System.Collections;
 
 public class ResetLevelController : MonoBehaviour {
 
     void OnTriggerEnter2D(Collider2D other){
         print("Reset collider enter:" + other.gameObject.transform.name);
     }
 
     void OnTriggerExit2D(Collider2D other){
         
         
         print("Reset collider exit:" + other.gameObject.transform.name);
     }
 
     void OnTriggerStay2D(Collider2D other){
         
         
         print("Reset collider stay:" + other.gameObject.transform.name);
     }
 }

When my other game objects pass over the text the first time I get the following debug output:

Reset collider enter:basketball Reset collider stay:basketball Reset collider exit:basketball

The problem is - this only ever happens on the first contact between the 2 objects, if I make the basketball pass the text another time, the triggers dont fire? I would like to understand why?

My real goal here is to have a textmesh where I can press it as a button as part of my GUI and then take some action but this is apparently surprisingly hard.
