checkout_cart_update_item_complete is not firing

Question

config.xml :-

  <events>
  <checkout_cart_add_product_complete> 
    <observers>
      <checkout_cart_product_add_after_handler> 
        <type>model</type> 
        <class>observertest/observer</class> 
        <method>addToCartAdditionalItem</method>  
      </checkout_cart_product_add_after_handler>
    </observers>
  </checkout_cart_add_product_complete>

   <checkout_cart_update_item_complete> 
    <observers>
      <checkout_cart_update_item_handler> 
        <type>model</type> 
        <class>observertest/observer</class> 
        <method>updateCartItem</method>  
      </checkout_cart_update_item_handler>
    </observers>
  </checkout_cart_update_item_complete>
 </events>

In the events tag you can see 2 event in which first one(checkout_cart_add_product_complete) is working fine but second one is not.

Where i'm doing wrong, please let me know.

Note:-

I also tried to use checkout_cart_update_items_after instead of checkout_cart_update_item_complete it's working fine but by using this event not getting updated cart total price (just getting old one). e.g- suppose before updating my cart if in my cart a product having 4 qty & it's subtotal is $80($20*4) & if i went to update 3 more qty(20*7=$140) then this time by using event checkout_cart_update_items_after i'm getting $80 on my event action(updateCartItem) but i want $140.

Thanks!!!

checkout_cart_update_item_complete is dispatched in Mage_Checkout_CartController::updateItemOptionsAction() ... haven't testet it, but method description says:

/**
 * Update product configuration for a cart item
 */
public function updateItemOptionsAction()

I'm not sure if this is used only for configurable products. You can try checkout_cart_update_items_after instead.

It's dispatched in Mage_Checkout_Model_Cart::updateItems() and should work for every cart update:

/**
 * Update cart items information
 *
 * @param   array $data
 * @return  Mage_Checkout_Model_Cart
 */
public function updateItems($data)
