Ajax + jQuery + CodeIgniter - problem - El Forum - 01-09-2012

Hello everybody!
I need display value of "input" field, where I use jQuery and Ajax.
I has view viewprofileedit.php
Code:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Here you can edit your profile</title>
[removed][removed]
[removed][removed]
[removed]
$(document).ready(function() {
  $('#save').click(function() {
   var item = $('#item').val();

   $.post("/profile/edit", { 'item' : item },
   function(data){
    alert(data.result);
   }, "json");
  });
});
[removed]
</head>
<body>
<form id="items">
  <p>
   &lt;input type="text" name="item" id="item" /&gt;
  </p>
  <p>
   &lt;input type="submit" name="save" id="save" value="Save Item" /&gt;
  </p>
&lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;

and controller, where I use method edit(), which should be add string "From the controller " to value of element with id="item".

Code:
&lt;?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
class Profile extends CI_Controller{

    function __construct()
    {
        parent::__construct();

        $this->load->helper('url');
        $this->load->library('my_auth');
    }
    function index(){        
        
        if (!$this->my_auth->is_logged_in()) {
            redirect('/auth/login/');
        } else {
            $this->load->view('viewprofile');
            redirect('/begin');
        }
    }

    function edit() {
        if (!$this->my_auth->is_logged_in()) {
            redirect('/auth/login/');
        } else {
            $item = "From the Controller: ".trim($this->input->post('item'));
            $array = array('result' => $item);
            echo json_encode($array);
        }
    }
    
    function editor() {
        if (!$this->my_auth->is_logged_in()) {
            redirect('/auth/login/');
        } else {
            $this->load->view('viewprofileedit');
        }
    }
}

But when I go to http://site.com/profile/editor and enter data into form and press button, I watch next:
{"result":""}
But I must get next alert message: "From the Controller: value_of_item_field"
What is my problem?
Thanks all.
