manually executing jquery ajax call instead of using remote => true in the link_to tag

gistfile1.haml

      li.links
        = link_to ccn.name, '#', :class => 'symptom_link grey', :id => "symptom-#{ccn.id}"
        javascript:
          jQuery(function() {
            jQuery(".symptom_link").click(function() {
              jQuery.ajax("/symptom/update_possible_causes/#{ccn.name.gsub(/\s/, '-').downcase}");
            });
  	  });
