Executing a function after each loop with animations has been completed

[VirtuosiMedia]

I'm having a little trouble with executing a function at the proper
time once the animations in an each loop have completed. Rather than
running after all animation is done, it instead runs instantly after
the calculations are done. I know that this is a common thing to do,
but I'm struggling with it for some reason. Here's the relevant code
using (the animations use Morph):

xValues.each(function(item, index){
        animated.start({
            'top': yValues[index],
            'left': item
        });
});
//I would like to run this function after the above animations have
finished
this.completed();
