Shuriken OnParticleCollision SendCollisionMessage doesn't work completely

Hi, I have a Shuriken LASER ParticleSystem with the collision and the SendCollisionMessages enabled. So I need to shoot this laser towards asteroids (Rigidbodies) thet every 4 shoots ere destroyed. I found the script for the asteroid in the Unity Documentation, and it works:

 using UnityEngine;
 using System.Collections;
 
 public class Example : MonoBehaviour {
     private ParticleSystem.CollisionEvent[] collisionEvents = new ParticleSystem.CollisionEvent[16];
     void OnParticleCollision(GameObject other) {
         ParticleSystem particleSystem;
         particleSystem = other.GetComponent<ParticleSystem>();
         int safeLength = particleSystem.safeCollisionEventSize;
         if (collisionEvents.Length < safeLength)
             collisionEvents = new ParticleSystem.CollisionEvent[safeLength];
         
         int numCollisionEvents = particleSystem.GetCollisionEvents(gameObject, collisionEvents);
         int i = 0;
         while (i < numCollisionEvents) {
             if (gameObject.rigidbody) {
                 Vector3 pos = collisionEvents[i].intersection;
                 Vector3 force = collisionEvents[i].velocity * 10;
                 gameObject.rigidbody.AddForce(force);
             }
             i++;
         }
     }
 }

This script adds a force to the asteroids and make them go away in opposite direction... When i change to this:

 if (gameObject.rigidbody) {
 
                 Debug.Log ("collision");
 
                 gameObject.rigidbody.GetComponent<AsteroidsRotation>().ApplyDamage (1);
             
             }

In the console i receive the collision debug (many at one time) but the ApplyDamage Function isn't called...

Is there a simpler way to do what i need? Or somethisng to change in my script?
