OnDrag OnPointerDown OnPointerUp does not work

Hey guys, its my first time here. I read all questions and solutions. Didn't find my solution. So what did i do:

• Adding EventSystem

• Physics 2D Raycaster attached to camera

• I have 2d Collider and raycast target on

I dont know what do i need to do. Could you please help me. I want to do this for an android joystick. If you have another solution, i would be grateful. Thx ^^ Here is my code

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 using UnityEngine.EventSystems;
 public class deneme : MonoBehaviour, IDragHandler, IPointerUpHandler, IPointerDownHandler
 {
     public void OnDrag(PointerEventData eventData)
     {
         Debug.Log("Ondrag");
     }
 
     public void OnPointerDown(PointerEventData eventData)
     {
         Debug.Log("OnpDown");
     }
 
     public void OnPointerUp(PointerEventData eventData)
     {
         Debug.Log("OnpUp");    
     }
 
    
 }
