scroll/swipe events controlling timeline for DPS

Hi,

Actually I am trying to controlling my timeline with events that I can use in my ipad. I export html from to Edge Animate, and I insert in Indesign to digital publishes (DPS).

I found this example:

I would like to know if there is a way to make the scroll smooth. I mean, if you give a little push with your finger and it just scrolls by itself and goes slower at the stop (don´t stop suddenly like in the example). Is this possible?

thank´s,

Rubén Afonso.
