Apply changes when click on the element

Well, @DanRathbun and @Aerilius, while I’m navigating in forums (here and sketchucation) and making some tests with onMouseMove and puts things out, I saw that I’m not understanding the concept of the model. I’m really having some struggle to understand various concepts and definitions that is difficulting my learning about things on sketchup.

Perhaps this is happening because I started dealing with Dynamic Components at first time that I had contact SU Ruby API here in work.

I’ll study more before doing a lot of questions here.
Thanks for your time. Cheers. =)
