NGUI Instantiate create on center

[outgoing]

Trying to create a copy of the object (NGUI) through Instantiate. Debug.Log (copy.transform.localPosition); prominence (-181.0, 230.0, 0.0), although in fact created a sprite to be in (0, 0, 0). What am I doing wrong? NGUI latest version.

1.  private void OnGUI()
2.     {
3.         if (GUI.Button(new Rect(10,10,100,50), "asdad"))
4.         {
5.             copy = Instantiate(gameObject) as GameObject;
6.             Debug.Log(copy.transform.localPosition);
7.         }
8. }

The solution was found through ...
NGUITools.AddChild(transform.parent.gameObject,gameObject).transform.localPosition = chacheTransform.localPosition;
If there is a better way direct
