xajax+smarty Question Urgent!

My refreshContent function cannot be called. I have been troubled by this problem for several days. I just can't find where the problem lies. I hope you can help me find it. Thank you!
The code is as follows:

xajax_smarty.php

require_once( 'Config/Config.inc.php');
require_once('xajax/xajax_core/xajax.inc.php');
$xajax = new xajax();
function loadContent($n){
Global $Smarty;
If($n==0){
$data[] = array('title' =>'helloworld','content' =>'

what is going on?

');
$data[] = array('title' =>'another item','content' => '

nothing fancy

');
          }
        else if($n == 1){
echo '=============';
                  $data[] = array('title' =>'Dynamically loaded' , 'content' => '

There you go

');
          }
$Smarty ->assign('posts' ,$data);
$ret = $Smarty ->fetch('post.html');
$Smarty ->clear_all_assign();
Return $ret;
}
Function refreshContent($formValues){//cannot be called
echo "ldkfjdl";
$response= new xajaxResponse();
$newContent = loadContent($formValues['select_page']);
$response ->addAssign('content' , 'innerHTML' , $newContent);
Return $response;
}
$xajax ->registerFunction('refreshContent');
$xajax->processRequest();

$Smarty ->assign('content' , loadContent(0));
$Smarty ->assign('xajaxjavascript' , $xajax ->getJavascript('xajax/'));
$Smarty ->display('main.html');
?>

<%{$post.title}%>

<%{$post.content}%>
