I am using animate in jQuery. I am getting problem to execute animate. It executes after test function I want to run this before test function

 $('.next').live('click',function() {
                    $('.ac_bgimage').animate({
                        left:"-100em"    
                    }, 15000 );
                    test();

This should work:

   $('.next').live('click',function() {
                $('.ac_bgimage').animate({
                    left:"-100em"    
                }, 15000, function() { test();} );
            });
