Wikitude

Hi, I'm new in wikitude, I need show a label and a image, well the image is easy to show but still I can't 

this is my code

 var label = new AR.Label("AUX AUX AUX", 100, {
         offsetY : 1,
         onClick : function() {
           label.text += "CLICK "
         },
         verticalAnchor : AR.CONST.VERTICAL_ANCHOR.TOP,
         opacity : 0.1
       });

   var imgOne = new AR.ImageResource("assets/imageOne.png");
   var overlayOne = new AR.ImageDrawable(imgOne, 1, {
      translate: {
         x:-0.15
      }

   });

   var pageOne = new AR.ImageTrackable(this.tracker, "*", {
      drawables: {
         cam: [label, overlayOne]
      },
      onImageRecognized: this.removeLoadingBar,
           onError: function(errorMessage) {
               alert(errorMessage);
           }
   });
},
