Are you getting the 'Raycast is working' output? If so, add:

  Debug.Log(hit.collider.name+", "+hit.collider.tag);

If you are not getting the 'Raycast is working' output, then verify that the object has a 3D collider, and that the collider is correctly aligned with the object.

The direction is part of the ray. Rays have an 'origin' and a 'direction'. I see nothing specifically wrong with your code, but check out the two areas I list above.
