JavaScript setInterval for opera mini and other mobile browsers

I'm facing problem using setInterval function in my website. I've a small section of my code below. I'm basically trying to increase the count by 1 and print it on screen.

<div id="test"></div>

<script>

var count = 0;
setInterval(function() {
    document.getElementById('test').innerHTML=count;
    count++;
}, 1000);


</script>
