iPad Touch event not working even though I used some specific codes

I am working on an epub so i have a task like when I click on the text it will be zoomed and at the same time it will play the audio. The code works fine in Safari browser:

$(document).ready(function() {
    var $ = jQuery.noConflict();
    <!-- document.addEventListener("touchstart", function(){}, true); -->
    var ua = navigator.userAgent, event = (ua.match(/iPad/i)) ? "touchstart" : "click";    
    $('.cls_txt').bind(event, function(e) { 
        document.getElementById('track').play();       
        document.getElementById('track').addEventListener('timeupdate', function (){ 
            var original=this.currentTime; 
            var ct=Math.round(original*10)/10; 
            console.log(ct); 
            if(ct>=0.1 && ct<=0.3){ $('#t1').addClass('sss'); }
            if(ct>0.4){ $('#t1').removeClass('sss'); }
        },false);
    });
});

but the above code works in some other pages. Help me.

What doesn't work? Does the audio play, but no zooming?

At first glance, the this.currentTime is not going to work--on the iPad or any browser--since this is not defined in the context of the event handler. You need to remember the video outside, as in:

var track = document.getElementById('track');
track.play();       
track.addEventListener('timeupdate', function (){ 
    var original=track.currentTime;
