not animating problem

not animating problem

Hi, I got ajax embedded in this div

  1. <div id="regaddcar" style="display:none;"></div>

When it's added it does something like this

  1. $("#regaddcar").html(data).addClass('ui-widget ui-widget-content');
  2. $("#regaddcar").fadeIn();
which works,

but on fading out, it does not animate, it only disappears

  1. $('#cancel').live('click',function()
  2. {
  3.        $('#regaddcar').fadeOut().removeAttr("class").html('');
  4.  });       
Did I missed something?

Thanks
