How to force check button to loose active state or focus?

How to force check button to loose active state or focus?

Hi

I change the background color of a checkbutton in a list element. It works like this:
good jsfiddle: https://jsfiddle.net/v1cavyvo/2/

<ul data-role="listview" id="liste" data-inset="true">

    <li>
         <a href="#" id="openExerciseLink74">
            <img src='' height="100" width="100">
            <h2>ddd</h2>
            <p><span>Wo: 3 x offen</span> (3 x 3 Wdh)</p>
         </a>
        <a onclick="changeColor(this);"
            id="background74"
            class="ui-icon-check activeYellow yellowUp
            yellowBackground">
        </a>
     </li>
</ul>

javascript:
function changeColor(obj) {
       $(obj).removeClass('yellowBackground');
       $(obj).addClass('greenBackground');
}

The problem is, that on the app on my samsung galaxy note 3, something like a focus or button pressed state remains on the check button. I don't want this state, but the new background color shown
Only for showing the wrong behaviour take a loot here: https://jsfiddle.net/v1cavyvo/3/

used evnironment:
        <script src=" http://code.jquery.com/jquery-1.11.1.min.js"></script>
        <script src=" http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>

Do you see any other possibility to force the behaviour working in 'good jsfiddle' for that it also works in my app?

Thanks
