使用magento 1.9中的ajax从视图页面更新购物车

Question

添加到购物车在视图页面上正常工作。项目动态更新。但更新购物车不会更新标题购物车项目。刷新后项目会更新。

结帐/购物车/项目/配置/ updatecart.phtml

<?php $_product = $this->getProduct(); ?>
<?php $buttonTitle = $this->__('Update Cart'); ?> 
<?php if($_product->isSaleable()): ?>
<div class="add-to-cart">
    <?php if (!$_product->isGrouped()): ?>
    <div class="qty-wrapper">
        <label for="qty"><?php echo $this->__('Qty:') ?></label>
        <input type="text" pattern="\d*" name="qty" id="qty" maxlength="12" value="<?php echo $this->getProductDefaultQty() * 1 ?>" title="<?php echo $this->__('Qty') ?>" class="input-text qty" />
    </div>
    <?php endif; ?>
    <div class="add-to-cart-buttons">
        <button type="button" title="<?php echo $buttonTitle ?>" class="button btn-cart" onclick="productAddToCartForm.submit(this)"><span><span><?php echo $buttonTitle ?></span></span></button>
        <span id='ajax_loader' style='display:none'><img src='<?php echo $this->getSkinUrl('images/opc-ajax-loader.gif')?>'/></span>
