update in controller

// either: step-by-step update with setValue
function fakeProgress(){
    var val = 0;
    var pInterval = setInterval(function(){
        $.progress.setValue(++val);
        if (val >= 100) clearInterval(pInterval);
    }, 30);
}

// this is how you customize the value text
$.progress.formatValue = function(val){ return (val / 100 * 360) + '°'};

// or: to specific value at once with animation (does not work on iOS)
$.progress.animate({
	value: 75,
	duration: 500
});
