How to add a callback funtion to this slideUp()?

$(".button").click(function(){                     
      $(".round").slideUp({duration:1000, easing:"sineEaseInOut"})
});


I tried:
$(".button").click(function(){                     
   $(".round").slideUp({duration:1000, easing:"sineEaseInOut"}, function(){ alert('done'); } );
});

But is not working...
