Recently my html guy implemented piechart using jquery plug -in name as easyPieChart just like in the following way.

html code:

<span class=chart pull-right data-percent=45 id=_percentUpdate>

    <div class=flip-container>

      <div class=flipper onclick=this.classList.toggle('flipped') id=conserHoursFlip>

       <div class=front percent></div>

       <div class=back percent></div>

      </div>

    </div>                                              

<span>

I want to change dynamically percent value through JavaScript or backbone.js,but I can't able to fix this.

can anyone help me.

Thanks.
