Issues with Edge parallax effect in DPS

i know there many threads (most 2013) using touch events control edge animaiton timeline. have tried several approaches including edgedocks / edgecommons.js -- have tried downloading js , linking locally. worked fine in browser, not on ipad. seems stuck on frame 1 , not causing animation crontolled stage scroll or touch events.

 

i tried adobe inspire edge banner tutorial here: http://www.adobe.com/inspire/2014/01/parallax-edge-animate.html

 

i downloaded edge files, published oam. placed in new folio, uploaded , viewd on ipad through content viewer , works fine.
here's code:

 

// map scroll position timeline position

var animationwidth = 3072;

var stagewidth = sym.$("stage").width();

var scrollpos = sym.$("stage").scrollleft();

var duration = sym.getduration();

var percent = scrollpos / (animationwidth - stagewidth);

var time = duration * percent;

 

// update timeline

sym.stop(time);

 

what need make work vertically? values/attributes need use. want create 768 x 5120 article in indesign , create various animations using parallax effect horizontal example?

 

thanks in advance.
