animate’s callback function (complete) executed at start?

I see two things wrong with this.

One, easing should be:

A string indicating which easing
function to use for the transition

And complete should be a function.

http://api.jquery.com/animate

alert('start ani');
$('.cellcontent').animate({
     left: '-=190'
   },
   {
     easing: 'swing',
     duration: 5000,
     complete: function(){
        alert('end ani');
    }
});
