title: With a jquery modular dialog how do I stop the form values from persisting?
body: <p>(Citing source at: <a href="http://jqueryui.com/demos/dialog/#modal-form" rel="nofollow noreferrer">http://jqueryui.com/demos/dialog/#modal-form</a>)</p>
  
  <p>As an example, this works great but each time the form is subsequently opened the user entered values remain. How can I stop this behavior? (the form will be used multiple times on the same page.</p>
