Почему функция обратного вызова в этой анимации Jquery будет выполняться раньше, чем анимация?

У меня есть этот javascript: 

        $('.carouselItem.' + currentCarouselItem).animate({left: '975px'}, 'slow', function(){
            $(this).removeClass('active');
            $(this).attr('style','');
            var nextItem = currentCarouselItem + 1;
            if (nextItem == 7) {
                nextItem = 1;
            }
            $('.carouselItem.' + nextItem).animate({left: '110px'}, 'slow', function(){
                $(this).addClass('active');
            });
            }
        })

Обратный вызов для первой анимации выполняется до завершения первой анимации.Любая идея, почему?

Вот полный код, если это будет более полезным: 

var currentCarouselItem = 1; //set carousel to first slide
    var runCarousel = 1;
    var carouselInterupt = 0;


function autoScroll(){

        if (runCarousel == 1) {
            if (carouselInterupt == 0){

            $('.carouselItem.' + currentCarouselItem).animate({left: '975px'}, 'slow', function(){
                $(this).removeClass('active');
                $(this).attr('style','');
                var nextItem = currentCarouselItem + 1;
                if (nextItem == 7) {
                    nextItem = 1;
                }
                $('.carouselItem.' + nextItem).animate({left: '110px'}, 'slow', function(){
                    $(this).addClass('active');
                });
                }
            })

            if (currentCarouselItem == 6) {
                currentCarouselItem = 1;
            } else {
                currentCarouselItem++;
            }

        }
    }

    setTimeout(autoScroll, 3000);

}

$(function(){

$(window).load(function(){

    autoScroll();

});

});

А вот затронутый HTML (много lorem ipsum :)): 

    <div id= "wrapper">
    <div id= "teasertext" class="active carouselItem 1">

У вас, кажется, есть дополнительная фигурная скобка }: 

 $('.carouselItem.' + currentCarouselItem).animate({left: '975px'}, 'slow', function(){
    $(this).removeClass('active');
    $(this).attr('style','');
    var nextItem = currentCarouselItem + 1;
    if (nextItem == 7) {
      nextItem = 1;
    }
    $('.carouselItem.' + nextItem).animate({left: '110px'}, 'slow', function(){
       $(this).addClass('active');
     });
  }   //<----- HERE
  })
...
