iTween FadeTo

I'm going crazy... I will do fade between 3 group of object (3 object that have 3 child each). I'm using iTween. It is work only for the first fade. After the first fade script must be deactivate the first group of object, but It doesn't... I don't understand...

 var OBJFirst : GameObject;
 var OBJSecond : GameObject;
 var SingleTouch : boolean = true;
 var DoubleTap : boolean = false;
 var Swipe : boolean = false;
 var AlphaHigh : float = 1.0;
 var AlphaLow : float = 0.0;
 var velocity : float = 1.0;
 var TimeDelay : float = 0.0;
 
 private var var_Fade : boolean = false;
 private var GoTouch : boolean = true;
 
 function Awake () {
 }
 
 
 function Start () {
 }
 
 function Update () {
 
 if (var_Fade){
 fun_Fade();
 }
 }
 
 function fun_Fade(){
      
      iTween.FadeTo(OBJFirst,{"a":AlphaLow, "time":velocity, "delay":TimeDelay, "onComplete":"fun_FadeFalse", "onCompleteTarget": OBJFirst});
      iTween.FadeTo(OBJSecond,{"a":AlphaHigh, "time":velocity, "delay":TimeDelay, "onComplete":"fun_FadeFalse", "onCompleteTarget": OBJSecond});
      }
   
     
 function fun_FadeFalse() {     // this must be deactivate first group and all child
 var_Fade = false;
 Manager.GoTouch = true;
 OBJFirst.SetActiveRecursively(false);
 }
 
 
 function On_TouchStart(gesture:Gesture){
 if (Manager.GoTouch){
 if (SingleTouch){
 Manager.GoTouch = false;
 OBJSecond.SetActiveRecursively(true);
 var_Fade = true;
 }
 }
 }

Help.
