title: Both onBlur and onChange not working with <input type="text"
body: <p>I have a standard input type text field that is supposed to trigger a Javascript whenever it is changed. First I tried onChange, however it just did nothing. Then I tried onBlur, but also here it did not do anything.</p>
  
  <p>HTML Code:</p>
  
  <pre><code>&lt;input type="text" size="1" class="inputbox" onblur="c();" name="qty" value="1" /&gt;
  </code></pre>
  
  <p>The Javascript should not be the problem, because I am triggering this with another select dropdown menu as well and there it works fine! Just on this text field it seems not to work. Anyways, here's the Javascript code:</p>
  
  <pre><code>function c() {
  $('#add4').fadeOut(function(){
          $('#add5').css('visibility', 'visible');
          document.u.submit();
  }); 
  }
  </code></pre>
  
  <p>I checked online, but could not find any relevant posts or hints in this regard whatsoever. Any ideas what's wrong?</p>
