title: Submit button doesn't work on enter
body: <p>I have several "submit" inputs on my form (this is caused by a framework I'm using), so to control what button is actually activated on "Enter" (as well as by "Go" button of Android keyboard), I have added this markup:</p>
  
  <pre><code>&lt;input type="submit" style="position:absolute;top:0;left:-100px;"
  onclick="$('#DefaultButton').click();return false;" /&gt;
  </code></pre>
  
  <p>I'm placing it in the very beginning, so that it's first in order, but still inside of the form.
  This works great in one of my applications, but not working at all in the other!</p>
  
  <p>Even more suprising is that in that other application, there is a case when there is 1 single submit, so it should be working as the default without any additional work, but it never worked. Even when I add this hidden submit - it doesn't work neither. I have checked via javascript the count of submits on the page - and it have shown me 2: one is the one visible to user, the other is this one I'm adding.</p>
  
  <p>Ok, I did javascript to handle keypress, it's working, but I don't like this aproach - I would prefer the natural way, when first submit acts as the default button.</p>
  
  <p>Also, I have checked on mobile - I thought there will be problem that "Go" button will not work - but it is working. So it's not working in desktop browser only.</p>
  
  <p>What can be the problem here? Is my submit missing any attribute?</p>
  
  <p>I can't post the whole page, cause it's huge, here is a simplified markup of that "real" submit button (it is generated by the framework):</p>
  
  <pre><code>&lt;input onclick="*Ajax javascript*; return false;" type="submit"
  name="DefaultButton" value="Continue" id="DefaultButton" tabindex="17"
  class="Button" /&gt;
  </code></pre>
  
  <p>Here is also the form tag (also generated by the framework):</p>
  
  <pre><code>&lt;form method="post" action="Signup.aspx" onsubmit="javascript:return WebForm_OnSubmit();"
  id="WebForm1" name="WebForm1"&gt;
  </code></pre>
  
  <p>UPDATE. I'd like to note again, that I made it working via handling onkeypress for keyCode == 13, I was just wondering why normal submit button doesn't react on Enter, as it should.</p>
