$('#beleg_sichern').click(function() {
    $('#dialog').dialog('open');
});

No nice way to do this really since the dialog button constructor only allows you to express the text of the button and the click function.

One way is to set these before submitting the form.

$("#dialog").dialog({
    bgiframe: true,
    autoOpen: false,
    height: 150,
    width: 600,
    modal: true,
    buttons: {
        Submit: function(ev) {
          var btn = ev.target;
          btn.value = 'someValue';
          btn.name = 'someName';
          btn.form.submit();
          $(this).dialog('close');
        },
        Cancel: function() {
            $(this).dialog('close');
        }
    }
});
$('#beleg_sichern').click(function() {
    $('#dialog').dialog('open');
});
