jQuery Div Refresh with jQuery Hide/Show Div

I have a page that refreshes a div:

<?php
/***************************************************************************************
Purpose: 	Page to display all open projects.
		
Maintenance History:
Date:		Name:			Action:	
----------------------------------------------------------------------------------------
06/14/2012	Nathan             	Created
****************************************************************************************/
//Is the user logged in?
define("_VALID_PHP", true);
require_once("init.php");
  if (!$user->logged_in)
      redirect_to("index.php");
  $row = $user->getUserData();
  $userid = $row['id'];

//Connect to the Database
require_once("config.php");

echo '<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
 $(document).ready(function() {
 	 $("#responsecontainer").load("response.php");
   var refreshId = setInterval(function() {
      $("#responsecontainer").load("response.php");
   }, 5000);
   $.ajaxSetup({ cache: false });
});
</script>';

//Begin Header
include("header.php");
echo '<center><h1>Current Projects</h1></center>';
echo '<div class="workplace">
<div class="newproject"><a href="' . $path . '/newproject.php"><img src="' . $path . '/images/newproject.png" width="75" height="76" /></a></br>New Project</div>
	<div id="responsecontainer">
	
</div>';
//Begin Footer
include("footer.php");
?>

Code (markup):

It's refreshing the div "responsecontainer" every 5 seconds to look for new projects. The data that it gets from response.php is here:

<? 
/***************************************************************************************

****************************************************************************************/

//Is the user logged in?
define("_VALID_PHP", true);
require_once("init.php");
  if (!$user->logged_in)
      redirect_to("index.php");
  $row = $user->getUserData();
  $userid = $row['id'];
  
//Connect to the Database
require_once("config.php");
$connect = mysql_connect($host,$username,$password);
mysql_select_db($database, $connect);

//Query the needed data
$result = mysql_query("SELECT p.id,
							userid,
							title,
							description,
							date_format(createdate,'%M %D %Y') createdate1,
							date_format(enddate,'%M %D %Y') enddate,
							complete,
							username,
							(select count(id) from comments where projectid = p.id ) commentcount
							FROM projects p 
							join users u on p.userid = u.id  
							where userid = " . $userid . " 
							and Complete = 0 
							order by createdate desc");
//jQuery code to hide/show Comments
echo '<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
        $(".slidingDiv").hide();
        $(".show_hide").show();
   $(".show_hide").click(function(){
   $(this).next(".slidingDiv").slideToggle();
});
});
</script>';

//Check to see if there are any open projects
if (mysql_num_rows($result) == 0)
  echo 'You have not started any projects</br></br></br></br></br>';
//If open projects list them
while($row = mysql_fetch_array($result))
  {
	if ($row['id'] > 0) echo '
<div class="projectboxpreview">' . '
	<div class="newprojectboxtitle">'	. '
		<a href="' . $path . '/projects/' . $row['id'] . '.php">' . $row['title'] . '</a>' . ' 
		<div class="pusername"> 
			Created By: ' . $row['username'] . '
		</div>' . '
	</div>' . 
$row['description'] . '</br>
			<a href="#" class="show_hide">Comments</a>
				<div class="slidingDiv">' . $row['commentcount'] . '
				
				</div>
			
</div>';
}
 ?>

Code (markup):

On the page load the div that is hidden is "Comments" and works as expected. Though after the page refreshes the div, the "Comments" are all expanded and the hide/show no longer works.
