I'm trying to embed the twitter widget with the standard code in cordova, but somehow it only creates the link instead of the widget

I'm trying to embed the widget in my phonegap/cordova app with the standard code:

<a class="twitter-timeline" href="https://twitter.com/Elevraadet_OG" data-widget-id="xxxxxxxxxxxxxxxxxx" data-chrome="noheader nofooter transparent noscrollbar" data-tweet-limit="16">Tweets af @Elevraadet_OG</a>
<script>
    !function(d,s,id){
        var js,
            fjs=d.getElementsByTagName(s)[0],
            p=/^http:/.test(d.location)?'http':'https';
        if(!d.getElementById(id))
        {
            js=d.createElement(s);
            js.id=id;
            js.src=p+"://platform.twitter.com/widgets.js";
            fjs.parentNode.insertBefore(js,fjs);
        }
     }(document,"script","twitter-wjs");
</script>

How ever this only creates the Tweets af @Elevraadet_OG link instead of the widget, how come this doesn't work?
