why not show search results(success: function (data)) in ajax call? i use of CodeIgniter. It does no error and no results

js:

Code:

$('#hotel').keypress(function () {
    var dataObj = $(this).closest('form').serializeArray();
    $.ajax({
        url: 'http://localhost/mehdi/admin/tour/search_hotel',
        data: dataObj,
        dataType: 'json',
        success: function (data) {
            $("#suggestion_tab").html('');
            $.each(data.name, function (a, b) {
                $("#suggestion_tab").append('<li>' + data.b + '</li>');
            });
            // Display the results
            ///alert(data);
        },
        "error": function (x, y, z) {
            // callback to run if an error occurs
            alert("An error has occured:\n" + x + "\n" + y + "\n" + z);
        }
        });
    });

CI_Controller

Code:

function search_hotel(){
        $searchterm = $this->input->post('search_hotel');
        echo json_encode($this->model_tour->search_hotel($searchterm));
    }

CI_Model

Code:

function search_hotel($searchterm)
    {
        $query = $this->db->order_by("id", "desc")->like('name', $searchterm)->get('hotel_submits');
        $data = array();
        foreach ($query->result() as $row)
        {
           $data[] = $row->name;
        }
        return $data;            
        //return mysql_query("select * from hotel_submits where name LIKE '".$searchterm."'");
    }

Code:

$query = $this->db->order_by("id", "desc")->like('name', $searchterm)->get('hotel_submits');

Code:

$query = $this->db->order_by("id", "desc")->like('name', $searchterm, 'after')->get('hotel_submits');
