OnControllerColliderHit works on 2 character controllers

Hi everyone, I have been reading alot and having a hard time to get the OnControllerColliderHit works on 2 character controllers. (one from enemy , another from player char)

This is the enemy side script. At the moment, when ever its on the floor, the hit.object.name is the floor. But when I try to debug hit.controller, its printing the enemy's controller (itself). I wonder why its is not able to detect my player ? I'm sure I have tag everything right. Thank you.

 function OnControllerColliderHit(hit:ControllerColliderHit)
 {
     hit.collider.renderer.material.color = Color.red;
         
     if(hit.gameObject.tag == "Player")
         print("hit");
     
     if(hit.controller.tag == "stage")    
         return;
 }
