Кнопка подтверждения заказа отсутствует в процессе оформления заказа opencart 2.0

Я создал модуль платежного шлюза ранее для версии 1.5, он работает отлично, теперь я обновился до 2.x, поэтому я начал работать со своими модулями, все работает нормально, за исключением того, что отсутствует окончательный порядок подтверждения.

вот ссылка на изображение http://i.stack.imgur.com/Ak4B1.png

я заменил старый код своим новым кодом, но он все равно не работает, и большая проблема в том, что он даже не показывает ошибку, так что я могу понять

Вот мой старый код

<form action="<?php echo $action; ?>" method="post" id="payment">

</form>
<div class="buttons">
  <div class="right"><a id="button-confirm" class="button" onclick="$('#payment').submit();"><span><?php echo $button_confirm; ?></span></a></div>
</div>

Новый код

 <form action="<?php echo $action; ?>" method="post" id="payment">

    </form>
     <div class="buttons">
        <div class="pull-right">
          <input type="submit" value="<?php echo $button_confirm; ?>" class="btn btn-primary" id="button-confirm" />
        </div>
      </div>
