Get data from controller by AJAX

Hi!

I tried get data from controller by AJAX but I wrote something wrong.
Here is my code:

CONTROLLER:

PHP Code:

$data['AcceptedServices'] = $this->AdminServices_model->GetAcceptedServicesAdmin(); // I get by result()

echo json_encode($data);
$this->load->view( 'admin/ServicesList', $data ); 


VIEW:

PHP Code:

    $(document).ready(function() {
            $('#DawajDane').click(function() {
                $.ajax({
                    url: '<?php echo base_url(); ?>admin/AdminMain/GetServices',
                    type: 'POST',
                    dataType: 'json',
                    success: function ( data) {
                        console.log(data);
                    },
                    error: function ( data ) {
                        console.log('error');
                    }
                });
            });
        }); 


I want display this data first in console, but in console i recive 'error'.
Where is the problem?
