I've create a custom module for import n products
(Prestashop 1.6.1.7)
is all ok,
but when I try to filter a search (there are 1882 records)
the filter doesn't work.
I've read other post about the problem but I don't understand if there is a problem into my controller or if I forget something.
I have one table (cpld_articles) where are stored these data

this is my controller

require_once (_PS_MODULE_DIR_ . 'forniture/classes/cpld.core.php');



class AdminFornitureController extends ModuleAdminController {



protected $position_identifier = 'id';



public function init() {







    // Set variables

    $this->context = Context::getContext();

    $this->table = 'cpld_subcategory';

    $this->article_table = 'cpld_articles';

    $this->className = 'cpld';

    $this->identifier = 'id';

    $this->_defaultOrderBy = 'id';

    $this->bootstrap = true;

    $this->lang = false;



    $this->addRowAction('edit');

    $this->addRowAction('view');

    $this->addRowAction('update');

    $this->addRowAction('import');



    $this->fields_list = array(

            'id' => array(

            'title' => $this->l('ID'),

            'align' => 'center', 

            'width' => 50,

            'type' => 'int'

        ),



        'id_parent' => array(

            'title' => $this->l('ParentID'),

            'width' => 50,

            'class' => 'fixed-width-xs',

            'type' => 'int'

        ),

        'categoria_app' => array(

            'title' => $this->l('Categoria > Sottocategoria'),

            'width' => 200

        ),

        'titolo' => array(

            'title' => $this->l('Titolo'),

            'width' => 150,

            'type' => 'text',

            'filter_key' => $this->table.'!titolo',

        ),

        'n_articoli' => array(

            'title' => $this->l('N° Articoli'),

            'width' => 50,

            'type' => 'int',

        ),

        'abilitato' => array(

            'title' => $this->l('Abilitato'),

            'type' => 'bool',

            'active' => true,

            'filter_key' => $this->table.'!abilitato',

            'class' => 'fixed-width-sm'

        ),

        //'abilitato' => array('title' => $this->l('abilitato'), 'active' => '1', 'class' => 'fixed-width-sm'),

        'ricarico' => array(

            'title' => $this->l('Ricarico %'),

            //'type' => 'editable',

            'width' => 50,

            'type' => 'int',

            'filter_key' => 'ricarico',

            'search' => true

        ),

        'reg_iva' => array(

            'title' => $this->l('IVA'),

            'width' => 50,

            'type' => 'int',

            'filter_key' => 'reg_iva',

            'search' => true

        ),

        'data_ins' => array(

            'title' => $this->l('Date Add'),

            'type' => 'datetime'

        ),

        'data_upd' => array(

            'title' => $this->l('Date Upd'),

            'type' => 'datetime'

        ),

    );



    // Call of the parent constructor method

    parent::init();



}

This is cpld.core.php

class cpld extends ObjectModel {
