mayavi view (azimuth, elevation, distance)

In the dummy program below I'm just trying to control the properties of some graphics objects with a slider.
The program works as intended but I would like to be able to control the view (the position and direction of the camera) from the program.
I normally do that with mlab.view(azimuth=None, elevation=None, distance=None, focalpoint=None,roll=None, reset_roll=True, figure=None) but that does not seem to work in this case.
What should I do instead ?
