Unable to save

Hello everybody,

I've been adding several instances of CKEditor using jQuery this way :

var config = {
      toolbar:
      [
         ['Source'],
         ['Save'],
          ['Cut','Copy','PasteText'],
         ['Print'],
          ['Undo','Redo'],
         ['Find','Replace'],
         ['SelectAll','RemoveFormat'],
          ['Bold','Italic','Underline','Strike'],
          ['NumberedList','BulletedList'],
         ['Outdent','Indent'],
          ['Link','Unlink','Anchor'],
          ['Format'],
          ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
          ['Image','Table','HorizontalRule'],
          ['TextColor'],
          ['Maximize', 'ShowBlocks']
      ]
   };

   $(".bloc-1 textarea, .bloc-2 textarea, .bloc-3 textarea").each(function(){
      CKEDITOR.replace($(this).attr('id'), config);
   });

The instances actually work fine but the save button stays grey, even when mouseovering it. Have I been leeking something ?

Thanks a lot
