Как добавить возможность вывода цены в поисковый запрос к2store?

Добрый вечер.Переделываю под себя шаблон на k2store В интернет магазине сделанном на k2store Установил модуль JA K2 Filter and Search Нашел файл отвечающий за вывод результатов поиска index.php/components/com_k2/templates/default/category_item.php в моем шаблоне .Получилось вывести фотографию товара Код

<!-- Item Image -->
<div class="catItemImageBlock">
<span class="catItemImage">
<a href="<?php echo $this->item->link; ?>" title="<?php if(!empty($this-
>item->image_caption)) echo K2HelperUtilities::cleanHtml($this->item-
>image_caption); else echo K2HelperUtilities::cleanHtml($this->item->title); 
?>">
<img src="<?php echo $this->item->image; ?>" alt="<?php if(!empty($this-
>item->image_caption)) echo K2HelperUtilities::cleanHtml($this->item-
>image_caption); else echo K2HelperUtilities::cleanHtml($this->item->title); 
?>" style="width:<?php echo $this->item->imageWidth; ?>px; height:auto;" />
</a>
</span>
<div class="clr"></div>
</div>
<?php endif; ?>
<?php if($this->item->params->get('catItemIntroText')): ?>
<!-- Item Image -->
<div class="genericItemImageBlock">
<span class="genericItemImage">
<a href="<?php echo $this->item->link; ?>" title="<?php if(!empty($item-
>image_caption)) echo K2HelperUtilities::cleanHtml($item->image_caption); 
else echo K2HelperUtilities::cleanHtml($item->title); ?>">
<img src="<?php echo $this->item->imageGeneric; ?>" alt="<?php 
if(!empty($item->image_caption)) echo K2HelperUtilities::cleanHtml($item-
>image_caption); else echo K2HelperUtilities::cleanHtml($item->title); ?>" 
style="width:<?php echo $this->params->get('itemImageGeneric'); ?>px; 
height:auto;" />
</a>
</span>
<div class="clr"></div>
</div>

и кнопку добавления товара в корзину в результатах поиска .Но вот с ценой за товар ни как не получается . Код который выводит кнопку добавления в корзину

Код

<!-- Add to cart button -->
<div class="span4 add_to_carts">
<div id='add_to_cart_<?php echo $this->item->id; ?>' 
class="k2store_add_to_cart" style="display: block;">
<input type="hidden" name="product_id" value="<?php echo $this->item->id; ?
>" />
<input type="hidden" id="task" name="task" value="" />
<?php echo JHTML::_( 'form.token' ); ?>
<input type="hidden" name="return" value="<?php echo base64_encode( 
JUri::getInstance()->toString() ); ?>" />
<input value="<?php echo JText::_('K2STORE_ADD_TO_CART'); ?>" 
type="submit" class="k2store_cart_button btn btn-primary basecolor_1" />
</div>
</div>


</div>  

</form>
<?php if(count(JModuleHelper::getModules('k2store-addtocart-bottom')) > 0 ): 
?> 
<div class="k2store_modules">
<?php echo K2StoreHelperModules::loadposition('k2store-addtocart-bottom'); ?
>
</div>
<?php endif; ?>

Код который выводит цену взят с файла addtocart.php Код

А именно Код

<!--base price-->
<div class="span4 product_prices">
<span id="product_price_<?php echo $this->item->id; ?>" 
class="product_price">
<?php  echo K2StoreHelperCart::dispayPriceWithTax($this->item-
>price, $this->item->tax, $this->item->params->get('price_display_options', 
1)); ?>
</span>
</div>
<?php endif; ?>

Цена при этом выводится но ее значение нулевое Как решить проблему как я понимаю не работает PHP на переменные

$this->item->price, $this->item->tax, $this->item->params-
>get('price_display_options', 1)); ?>
