[Qt-qml] QML models and components.

[Lars Kinnunen]

 Hi, I am trying to understand how QML models and components work, while
trying to understand demo code, I ran into this problem. I am wondering
how it is supposed to work. console message is supposed to return 100,
but it returns 0, where is the glitch?

 And as a bonus, how do I get First_Child to show.

 BR, Lars
