Problem is min cart is not reloading

Answer 1

As per as,your comment,AddtoCart is execute from mcartAction.

I have seen that your tried to return some block 'minicart_head','checkout/cart_sidebar' etc from that Action using $this->getResponse()->setBody($html);

I assume that your minicart section <div id="header-cart" has been updated properly and you have issue with class="bucket-wrap" section qty update.

If you will return Current Cart qty from mcartAction then it will work perfectly.

$result[html]=$html;
  $result[qty]=Mage::getSingleton('checkout/cart')->getSummaryQty();;
  $this->getResponse()->setHeader('Content-type','application/json',true);
  $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));

Note: I have return JSON at here.So need to change something at Ajax success method
