title: Textarea not working with jQuery live keyup function
body: <p>I'm trying to build a tag friend system for a personal project. I've found some great tutorials online but right now i'm stuck.</p>
  
  <p>Nothing happens when i type in @ in the tagbox. Display and msgbox should slide down so users can select a friend they want to tag. </p>
  
  <p>What am I doing wrong?</p>
  
  <pre><code>&lt;div id="tagbox"&gt;
      &lt;div class="textarea"&gt;
          &lt;textarea id="contentbox" name="contentbox"&gt;&lt;/textarea&gt;
          &lt;div id='display'&gt;&lt;/div&gt;
          &lt;div id="msgbox"&gt;&lt;/div&gt;
          &lt;button type="submit" id="tag_button" value="Update" name="submit"&gt;Add&lt;/button&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>And here's the AJAX/jQuery part:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      $(document).ready(function() {
          var start=/@/ig;
          var word=/@(\w+)/ig;
  
          $('#tagbox .textarea textarea[name="contentbox"]').live("keyup",function() {
              var content=$(this).text();
              var go= content.match(start);
              var name= content.match(word);
              var dataString = 'searchword='+ name;
  
              if(go.length&gt;0) {
                  $("#msgbox").slideDown('show');
                  $("#display").slideUp('show');
                  $("#msgbox").html("Type the name of someone or something...");
                  if(name.length&gt;0) {
                      $.ajax({
                          type: "POST",
                          url: "addfriends.php",
                          data: dataString,
                          cache: false,
                          success: function(html) {
                              $("#msgbox").hide();
                              $("#display").html(html).show();
                          }
                      });
                  }
              }
              return false();
          });
  
          $(".addname").live("click",function() {
              var username=$(this).attr('title');
              var old=$('#tagbox .textarea textarea[name="contentbox"]').html();
              var content=old.replace(word,""); 
              $('#ws3 .textarea textarea[name="contentbox"]').html(content);
              var E="&lt;a class='red' contenteditable='false' href='#' &gt;"+username+"&lt;/a&gt;";
              $('#tagbox').append(E);
              $("#display").hide();
              $("#msgbox").hide();
              $('#ws3').focus();
          });
      });
  &lt;/script&gt;
