Lazy loading in table view/scrollview

I need help in implementing lazy loading. I'm considering using tableview or scrollview but which is better performance wise?

Can anyone post some code in how to implement lazy loading in tableview?

I have around 40 rows of data. I want to load first 5 rows then 3 rows each time it reaches before the end of table.

here is my tableView creation:

interfaces.container = Ti.UI.createTableView({
        width: Ti.Platform.displayCaps.platformWidth, layout:'vertical',
        height:Ti.UI.FILL,
        top:100,
        contentWidth: 'auto', //backgroundColor:'blue',
        contentHeight: 'auto',
        _clear: function() {
            if (this.children != null) {
                var children = this.children;
                for (var i = 0; i < children.length; i++) {
                    this.remove(children[i]);
 
                }
            }
        }
    });
