Model disappears after a while

Hi, 

I am trying to make an aplication where a 3D model is moving around the screen. I have more or less managed this part, however the problem is that after a little bit the model disappears and reappears somewhere else. I assume this is because of the onLocationChange method which is called when the device location is updated. My question is whether or not it is possible to have this method called only after the user clicks on the model?

So the disired behavior would be to have the app create the object automatically when it is started but then hold on creating more until the current object is clicked.

Thanks
