I have this in my World class

var label = new AR.Label("This is a test", 0.30, {
  offsetX: 0,
  offsetY: -0.20,
  style:{
  textColor: "#ffffff",
  backgroundColor: "#000000"
  }
  });

I've added it to the Trackable2DObject. Its hows up on the screen. In multiple fuctions in the World class I have called

this.label.text = "Here";

The text NEVER changes. I can't for the life of m,e figure out what is going on.

I have tried World.label.text = "Here";

Nothing

Any help please. I've spent hours trying to change the text in a label!!!!!!!!!
