The JsHelper in CakePHP 1.3 has replaced the AjaxHelper from CakePHP 1.2.  I recently tried to implement the JsHelper without very much success; perhaps if I would have read the documentation more closely it would have been quite obvious what my mistake was.  So in case you're like me and often skim over long documentation of a helper when you just need one function (in my case $this->Js->submit()) then you can often miss very important information.  This article will hopefully help clarify it.
