Problem with iTween and instantiated path

Hi everyone! I have just started to use iTween (don't know much about it). I am making an endless runner for which I instantiate my prefab with iTweenPath script attached to it(from the iTween Visual Editor). The problem is when I instantiate the prefab(with which I have a iTween path attached, namely p2), the function iTweenPath.GetPath("p2") throws an error that it cant find the path "p2" (but I just instantiated it, and the name hasn't changed at all). Am I doing something wrong? Please help.

 void Start () {
 
         CurrPref =  Instantiate (pref1, new Vector3 (15, 0, 0), Quaternion.identity) as GameObject;
         CurrPref.name = "p2";
         CurrPref.GetComponent<iTweenPath> ().nodes.Clear ();
         CurrPref.GetComponent<iTweenPath> ().nodes.Add (new Vector3 (CurrPref.transform.position.x - 5,0,0));
         CurrPref.GetComponent<iTweenPath> ().nodes.Add (new Vector3 (CurrPref.transform.position.x + 5,0,0));
         CurrPref.GetComponent<iTweenPath> ().pathName = "p2";
         
         iTween.MoveTo (gameObject,iTween.Hash("path",iTweenPath.GetPath("p1")
                                               ,"time",1
                                               ,"easetype",iTween.EaseType.linear
                                               ,"OnComplete","MoveNext"
                                               ,"OnCompleteTarget", gameObject));
         
     }
 
 
     void MoveNext () {
         iTween.MoveTo (gameObject, iTween.Hash ("path", iTweenPath.GetPath("p2")
                                                 , "time", 1
                                                 , "easetype", iTween.EaseType.linear));
     }
