Cannot add delegate to slider onChange

[Shifty Geezer]

I can add a delegate via code to a slider for its Finished event thusly...

slider.onDragFinished = CallbackMethod;

However, the same doesn't work for onChange event and the description for onChange specifies it as a list rather than a delegate. How do I add a delegate on onChange?

EventDelegate.Add(slider.onChange, YourDelegate);
