How do to a shopping cart automatically update the value of the goods for cash on delivery?

Hi,

 

Sorry for my English,

 

How do to a shopping cart automatically update the value of the goods for cash on delivery? I've done already such changes in blockcart.php that I added functionality to doing cash on delivery. Here they are:

if(strstr($product['name'], "Elfa"))
		{
			$cod_cost = 5;//Tools::displayPrice(5, $currency);
			//$shipping_cost = 5;
		}
		else
		{
			$cod_cost = Tools::displayPrice(0, $currency);
			//$shipping_cost = Tools::displayPrice($base_shipping, $currency);
		}	
		/*Koniec kodu do okreslania ceny pobrania*/
		
		if(strstr($product['name'], "Elfa"))
		{
			$totalToPay = $params['cart']->getOrderTotal($useTax) + $cod_cost;
		}
		else
			$totalToPay = $params['cart']->getOrderTotal($useTax);

But the shopping cart automatically ie without refreshing the page does not update the status of the goods for cash on delivery. Where and how I can change this? I need to change that the shopping cart will be update the value of cash on delivery without refreshing.

 

Thanks for any help.
