Drupal JQuery Issue - Need some help
You should never use simple document ready in Drupal.

Drupal Behaviors was created specifically to address issues like yours. Nice entry manual can be found here.

Quick example:

(function($) {
  Drupal.behaviors.yourmodule = {
    attach: function (context, settings) {
      // your code here
    }
  };
})(jQuery);


In your code, remember to use context, like $('input[type=radio]') should become $('input[type=radio]', context)
