HoloLens airtap and instantiate object and then tap to move it around with Gaze and tap to place it on real world surface

I am trying to tap and instantiate a box then move it with my gaze on another tap place it at a place with spatial mapping. I am able to do it but the problem is that when I place the object with the final tap, one more box is getting created in front of me due to tapping. I have instantiated the Box in IInputClickHandler.OnInputClicked function. Any suggestions?

 {
     var instance = Instantiate(prefab);

     instance.gameObject.transform.position = GazeManager.Instance.GazeOrigin + GazeManager.Instance.GazeNormal * 1.5f;

     var tapToPlace = instance.gameObject.AddComponent<TapToPlace>(); //----------

     tapToPlace.SavedAnchorFriendlyName = (++this.count).ToString(); //-----------

 private void Update()
 {
     if(!this.loaded && (WorldAnchorManager.Instance.AnchorStore != null))
     {
         var ids = WorldAnchorManager.Instance.AnchorStore.GetAllIds();

         foreach(var id in ids)
         {
             var instance = Instantiate(this.prefab);

             WorldAnchorManager.Instance.AttachAnchor(instance.gameObject, id);
         }
         this.loaded = true;
         this.count = ids.Length; // --------------
