title: event.preventDefault not working
body: <p>I have this simple code here, nothing too advanced.</p>
  
  <pre><code>    $("input#send").submit(function(event){
        event.preventDefault();
      $.ajax({
          type: 'POST',
          url: add.php,
          data: data,
          success: success,
          dataType: dataType
      });
  });
  </code></pre>
  
  <p>Whever I click on the "send" button, the <code>event.preventDefault</code> function doesn't work, and the page loads.</p>
  
  <p>Any ideas why?</p>
