Lazy loading for scrollview

Hi guys,

I want to apply lazy loading on a scrollview. The code I have works in tableview but not on scroll view. So, how can I do this?

Here is the code for tableview lazy loading:

interfaces.container.addEventListener('scroll',function(e)
    {
        if (data.lastIndex === 0) 
        {
            return;
        }
 
        var offset = e.contentOffset.y;
        var height = e.size.height;
        var total = offset + height;
        var theEnd = e.contentSize.height;
        var distance = theEnd - total;
        Ti.API.info(offset + ', ' + height + ', ' + total + ', ' + theEnd + ', ' + distance);
        if (distance < lastDistance)
        {
            var nearEnd = theEnd * .9;
 
            if (!data.updating && (total >= nearEnd))
            {
                if (indexLoaded < magArray.length) {
                    //interfaces.lbl_updating.visible = true;
                    //interfaces.container.scrollable = false;
                    data.updating = true; 
                    Ti.API.info('begin update');
                    //loadBooks();
                }
            }
        }
        data.lastDistance = distance;
    });

I'm building for android, using 3.1.1 and 2.3.3 android api.
