The problem lies inside the html code:

<div>
<form>
<div>    
</div>
</div>
  <input type="submit" value="Verify" name="verify" id="verify" class="button">
</form>

Because there is one redundant </div>, the <input> was treat outside the form, hence capybara cause those error. After delete the redundant </div>, everything works fine.
