[Seaside] callback + onClick

[Hilaire Fernandes]

In the following example the callback is not called.

And no, it is not because the dialog is closed.

html anchor
    callback: [Transcript show: 'hello';cr];
    onClick: 'JavaScript:window.close()';
    with: 'Fermer'].

How should it be done to get execution both server and client side?
