Need help with layout scrolling with touch.

Hello, guys. I am developing a mobile game for the first time and I`m just starting working with touch object, so I can`t understand some nuances.

I need to make a scrolling layout in Y-axis in the way like mobile browsers do, so I made this:

But there is a problem: when I am holding my Touch, it works OK, but when I finish holding, layout is scrolling to the edge bottom.

Oh, it`s really cool and works as real browser. It has some inertia, so looks more smoothed. Thank you a lot for doing such a nice job, bibirez!
