Adding new tabs and fields to Prestashop products' back office

[KServices]

Hello,

I need help in the development of my module, i followed this pretty useful tutorial 'http://nemops.com/prestashop-products-new-tabs-fields/#.Wl3gVKjiaM8', to add a new tab in the products back office

But i don't know where execute my sql function when click on 'save and stay' button

My tpl

<div class="form-group">
  <input name="configurator_shipping" type="number" step="0.01">
  <label for="configurator_shipping">Frais de port</label>
  <div class="panel-footer {if version_compare($smarty.const._PS_VERSION_,'1.6','<')}margin-form{/if}">
    <button class="button btn btn-default" id="cancelConfiguratorProduct" name="cancelConfiguratorProduct" type="submit"><i class="process-icon-save"></i> {l s='Cancel' mod='configurator'}</button>
    <button class="button btn btn-default pull-right" id="submitConfiguratorProduct" name="submitAddproduct" type="submit"><i class="process-icon-save"></i> {l s='Save' mod='configurator'}</button>
  </div>
</div>

And in my module PHP

public function hookDisplayAdminProductsExtra($params)
{
  $this->smarty->assign(array('product' => $product));
  return $this->display(__FILE__, 'product-extra.tpl');
}

am trying to catch the click event with the hookActionProductSave And hookActionProductUpdate

But these function aren't executed. So where can i find my posted values  ?

Does someone have an idea ?

Please follow the tutorial properly. you will have the answer.

newfieldstut.php:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

public function hookActionProductUpdate($params) {     // get all languages     // for each of them, store the new field       $id_product = (int)Tools::getValue('id_product');       $languages = Language::getLanguages(true);     foreach ($languages as $lang) {         if(!Db::getInstance()->update('product_lang', array('custom_field'=> pSQL(Tools::getValue('custom_field_'.$lang['id_lang']))) ,'id_lang = ' . $lang['id_lang'] .' AND id_product = ' .$id_product ))             $this->context->controller->_errors[] = Tools::displayError('Error: ').mysql_error();     }   }

[KServices]

 /**
    * hookActionProductUpdate
    *
    * Product Update
    * 
    **/
    public function hookActionProductUpdate($params)
    {
        $id_product = (int)Tools::getValue('id_product');
        var_dump(Tools::getValue('configurator_shipping'));
        die();

    }

This function is already in my newfieldstut.php but i don't understand why it is never called.

Up ! 

I found a way to get around my problem with an ajax request but i don't like this solution.

Why my hookActionProductupdate is never called ?
