BO custom columns filter & sort issue

[outlet.ee]

I added 2 custom columns to the admin catalog, called 'supplier_reference' and 'myydyd' (meaning 'sold'). There is an extra field in DB for 'sold', and supplier reference field is already there in ps_product table.

The extra columns are showing but the filter and sorting for 'sold' do not work. Supplier reference filter works but sorting has issue with pagination.

Files modified:

src/PrestaShopBundle/Resources/views/Admin/Product/CatalogPage/Lists/products_table.html.twig: added

          <th>
          {% include '@PrestaShop/Admin/Helpers/range_inputs.html.twig' with {
              'input_name': "filter_column_myydud",
              'min': '-1000000',
              'max': '1000000',
              'minLabel': "Min"|trans({}, 'Admin.Global'),
              'maxLabel': "Max"|trans({}, 'Admin.Global'),
              'value': filter_column_myydud,
              'disabled': filters_disabled,
            } %}
          </th>

src/PrestaShopBundle/Resources/views/Admin/Product/CatalogPage/Lists/list.html.twig: added  
 

        <td class="text-center">{{ product.myydud|default('0'|trans({}, 'Admin.Global')) }}</td>       

/src/PrestaShopBundle/Entity/AdminFilter.php: added

 

            'filter_column_supplier_reference' => FILTER_SANITIZE_STRING,
            'filter_column_myydud' =>[
                'filter' => FILTER_CALLBACK,
                'options' => $filterMinMax(FILTER_SANITIZE_NUMBER_INT),
            ],

/src/Adapter/Product/AdminProductDataProvider.php, added

 

            'supplier_reference' => ['table' => 'p', 'field' => 'supplier_reference', 'filtering' => self::FILTERING_LIKE_BOTH],
            'myydud' => ['table' => 'pc', 'field' => 'myydud', 'filtering' => ' %s '],      

 

Is there any more files to edit to make the filters ans sorting work, or more to edit at the files already edited?
