Yes, but as I said, that only works with real closures.

You should not combine an AJAX and a traditional callback. They will
not be guaranteed to run in the right order. Instead do everything
with AJAX along these lines:

html anchor
    onClick: (html jQuery ajax
        trigger: [ :values | tempvalues := values ] passengers: ...;
        callback: [ ... does something with temps ... ];
        onSuccess: html javascript refresh);
    with: ...
