Touch in Phase ended

Hi there I have a sprite on screen . i use two separate code for TouchPhase.Began and TouchPhase.Ended . i like to run code when i touch up on sprite ( in TouchPhase.Ended ) but when i touching other position on screen and move my finger on sprite and then up my code get run .

 if (Input.touchCount == 1)
         {
             
             Vector3 wp = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
             Vector2 touchPos = new Vector2(wp.x, wp.y);
 
             Vector2 touchp = touchPos ; 
 
             if (Input.GetTouch (0).phase == TouchPhase.Began) {
                 touchp = Input.GetTouch (0).position;  
 
             }
 
 
             if (coll2D == Physics2D.OverlapPoint (touchPos)  ) {
 
                 if (Input.GetTouch (0).phase == TouchPhase.Began) {
                     SpRenderer.color = new Color (1f, 1f, 1f, 0.7f);
                 }
 
                 if (Input.GetTouch (0).phase == TouchPhase.Ended && coll2D == Physics2D.OverlapPoint (touchp)) {
                     
                     if (transform.position.y == StartPosition)
                         CanMoveUp = true; 
                     if (transform.position.y == TargetPosition)
                         CanMoveDown = true; 
 
                     SpRenderer.color = new Color (1f, 1f, 1f, 1f);
                 }
 
             } else if (coll2D != Physics2D.OverlapPoint (touchPos)) {
                 SpRenderer.color = new Color (1f, 1f, 1f, 1f);
             }
         }
