Can't remove cancel buttom from star rating plugin

I'm using the latest version of the star rating plugin from http://www.fyneworks.com/jquery/star-rating/ I have added the following to my document ready function, but the cancel button still shows. What am I doing wrong?

  1. $('input').rating('required', false);
I'm getting this error in Firebug

$.fn.rating[arguments[0]] is undefined
