HI Dennis,
1.why did you do all the logic inside the renderer? this is a best practice? if yes can you please explain why?
To put the code (which possible in the onBefore/after/init ) is not more cleaner ? like following JSBIN
2. As my example I need also to bind property when the value change (listen to change event )
so where you put the code to handle the change in the selection ?
