[jQuery] event fires exponentially

[Jan Limpens]

Hi guys,

I have this piece of innocent looking code:

<script>
$(document).ready(function(){
        $form = $('#filter-form');
        $form.ajaxForm({
                //dataType: 'json',
                success: function(){
                        alert("peng");
                },
                target: "#layout-child-output"
        });
        $('input', $form).change(function(){
                $form.submit();
        });
})
</script>

If I check one checkbox, I get one submit, for 2 2, however for 3 4,
for 4 16, and so on until the server crashes.

Any idea what is wrong here?
