Not really sure what you mean here. Are you saying this is a known
problem, and I should not expect it to work?

Yes, it does. The request is sent like this:

$.ajax({
url: url,
data: $form.serialize(),
dataType: 'html',
success: function (html, textStatus) {
$report
.html($('#report', html).html())
.css({
opacity: 1.0
});
style_preview_table();
}

And I have verified that all the non javascript portions of the
template are executed, but none of the javascript ones are.
