title: How to override HTML5 input number step function? Using jQuery
body: <p>I want to change the step on the HTML5 number inputs of my webapp. I want 100 by 100 instead 1 by 1.</p>
  
  <p>I have tried this:</p>
  
  <pre><code>$("#mynumberinput").keydown(function(e){
      if (e.keyCode == 38) // Arrow-Up
      {
        $(this).val(parseInt($(this).val() + 100));
      }
      if (e.keyCode == 40) // Arrow-Down
      {
        $(this).val(parseInt($(this).val() - 100));
      }
  });
  </code></pre>
  
  <p>But didn't work. How can I achieve this?</p>
