jquery, ajax and CKEditor - how to “unbind” a CKEditor insta

Hey, I'm using jquery, ajax and CKEditor:

$( '.ckeditor' ).ckeditor();

The first time the page is loaded through ajax the ckeditor() is fired off without a hitch. The second time it fails. Normally when binding you do something like:

.unbind('click').bind('click',function{...})

What do I do to unbind ckeditor()?
