Loading page into div is too quick

Loading page into div is too quick

Hi, I have problem with loading page into div element. All is working, only one problem is timing.
My function:
  2. function changePage(Id){     
  3.       $("#content-page").fadeOut(200);
  4.       $("#content-page").load("content_page.php", {id: Id}, function(){ $("#content-page").fadeIn(200)});
  5.  }
After I click in menu (onclick="changePage(this.id);"), element is not directly fades out, loads content and fades in. Element loads new content than fades out an fades in. Where is problem please?
