title: Update row status using ajax
body: <p>I am currently trying to program my first ajax interface using Rails.</p>
  
  <p>The application currently shows a table populated with list items. The user has to approve or reject each of the list items. I currently have an edit link at the end of each row that shows a form in which I can approve the list item.</p>
  
  <p>I am thinking on using a checkbox instead of the edit link. When the user clicks the checkbox I want to update the database with the status, user name and date/time without leaving this page.</p>
  
  <ol>
  <li>What steps should I follow? </li>
  <li>Can I use a checkbox or am I
  restricted to buttons?</li>
  <li>What xxx_remote helper should I use?</li>
  <li>How can I update the checkbox state with the results of the ajax call?</li>
  </ol>
