[Not Solved]Instintiated gameobject(sprite) wont load on scene

Hello,

In my code i am instantiaing a gameobject with a sprite multiple times. But only the original gameobject will load the sprite at the correct place. but the others ones wont.

(Im still a newbie so code wont look to nice)

edit: So i made a few changes, but i still have the same problem even though the objects arent in the same place anymore.

Instantiate code:

 void Start () 
 {
     PlaceBlocks();
 }


 void PlaceBlocks()
 {
     for( int i = 0 ; i <= 6 ; i++)
     {
         GameObject _go = (GameObject)Instantiate( _letterBlock ) as GameObject;
         _go.transform.position = Camera.main.ScreenToWorldPoint(new Vector3((_blockPosX[0]),(_blockPosY[i]),-2));
         this._letterBlockList.Add(_go);
     }

     for( int i = 0 ; i <= 5 ; i++)
     {
         GameObject _go = (GameObject)Instantiate( _letterBlock ) as GameObject;
         _go.transform.position = Camera.main.ScreenToWorldPoint(new Vector3((_blockPosX[1]),(_blockPosY[i]),-2));
         this._letterBlockList.Add(_go);
     }
 }

}

Instantiated object code:

 void Start () 
 {
     
     CreateButtons();
     
 }
 
 // Update is called once per frame
 void Update () {

     if(Input.GetKeyUp(KeyCode.A)){
         CreateButtons();
         print ("aaaargh");

     }
 }
 
 void CreateButtons()
 {
     
     string _textPath = "Assets/Texture/button 3.png";
     Texture2D _buttonText = (Texture2D)Resources.LoadAssetAtPath(_textPath, typeof(Texture2D));
     
     SpriteRenderer renderer = gameObject.GetComponent<SpriteRenderer>();
     Sprite sprite = new Sprite();
     sprite = Sprite.Create( _buttonText, new Rect(0,0,400,400), new Vector2 (0.5f,0.5f),250.0f);
     renderer.sprite = sprite;
     renderer.material = _dfltMaterial;
     
     
 }

 void OnMouseDrag()
 {
     _moveObject.x = Camera.main.ScreenToWorldPoint(Input.mousePosition).x;
     _moveObject.y = Camera.main.ScreenToWorldPoint(Input.mousePosition).y;
     _moveObject.z = -2;

     transform.position = _moveObject;
 }

}
