Now the knobValue is in the initial config, it is respected.

We can set the knobValue in the initial config and the knob will take
that value when it is initially rendered. Still there is an issue when
the turn event is fired for first time when we put it inside a carousel
with knobValue in initial config.
Fixed the initial setting of the value

Now the knobValue is set initially inside the painted event instead of
the init event. This is to fix issues when the turn event is fired for
the first time without the component being rendered.
