for Newyork - Responsive Prestashop Theme

Hi, how can I change the products order in TABS PRODUCTS ISOTOPE if is set \"All products from certain category\" (showing products added by date)

Ex: In TABS PRODUCTS ISOTOPE at Tab Content i choose \"All products from certain category\" and at \"Select a category\" i choose my category \"new girl skirts\" but on my homepage it shows the first added product from \"new girl skirts\" and not the newest :(

*** update *** 

searched in public tickets and found a solution

made this changes:

case \'category\':
                    $category = new Category($fieldTabProductsIsotope->tab_content, $id_default_lang);
                    $products = $category->getProducts($id_default_lang, 1, $maxProductCount,\'date_upd\',\'DESC\');
                    break;
