title: Fire event when mesh position updated in Babylon.JS
body: <p>I have a react app, and when I type in a text box it updates the position of a mesh inside a BabylonJS canvas. I need to be able to do this in reverse - update the text box when a gizmo is used to move the mesh. I don't know if this is possible with an event or another way. </p>
  
  <p>Any help would be highly appreciated.</p>
