ajax in plugin

[surferbloggy]

hi! I've added ajax to wordpress on the viewer-facing side it is a form filled by ajax when is entered email and password it worked, now it doesn't work anymore even if I use the originally code from wp codex:

function myplugin_js_header() // this is a PHP function
{
  // use JavaScript SACK library for Ajax
  wp_print_scripts( array( 'sack' ));

  // Define custom JavaScript function
?>
<script type="text/javascript">
//<![CDATA[

   function myplugin_cast_vote( vote_field,vote2_field, results_div )
{
       alert("hello");
   var mysack = new sack( 
       "<?php bloginfo( 'wpurl' ); ?>/wp-admin/admin-ajax.php" );    
  
  mysack.execute = 1;
  mysack.method = 'POST';
  mysack.setVar( "action", "my_special_action" );
  mysack.setVar( "vote", vote_field.value );
  mysack.setVar( "results_div_id", results_div );
  mysack.onError = function() { alert('Ajax error in voting' )};
  mysack.runAJAX();
  
  return true;

} // end of JavaScript function myplugin_cast_vote
           
           
           
//]]>
</script>
<?php
} // end of PHP function myplugin_js_header
    
    

function my_action_callback() {
    // Check request came from valid source here
    // TO DO!
    
    // read submitted information
    
    $vote = $_POST['vote'];
    $results_id = $_POST['results_div_id'];
    
    // Put your vote processing code here
    // In this example, assume 
    //  a) The processing code sets global
    // variable $error to a message if there is an error
    //  b) If there is no error, $results contains
    // the HTML to put into the results DIV on the screen
    // Here you can even access the database by using the
    // global $wpdb
    $error = "";
    $results = "HTML to put into the results DIV on the screen";
    
    if( $error ) {
       die( "alert('$error')" );
    } 
    
    // Compose JavaScript for return
    die( "document.getElementById('$results_id').innerHTML = '$results'" );
}

and

add_action('wp_ajax_my_special_action', array(&$this, 'my_action_callback'));
            add_action('wp_ajax_nopriv_my_special_action', array(&$this, 'my_action_callback'));

it worked beforer after that i write the ajax code for admin side, i include it in the main php file of the plugin do you think
