Full page cache problem in magento 2

As the two above told issues are closed that's why I am posting this .

I am using magento 2.1.8. I my custom theme app\design\frontend\Sample\theme-frontend-shop\Magento_Catalog\templates\product\view\form.phtml I have done

`
$quoteId = $objectManager->get('Magento\Checkout\Model\Session')->getQuoteId();
$currentItemCount=0;
if(!empty($quoteId)){
$cartItems = $objectManager->get('\Magento\Checkout\Model\Session')->getQuote()->getAllVisibleItems();
$itemsIds = array();
foreach ($cartItems as $cartItem) {
$itemsIds[] = $cartItem->getProduct()->getId();
}

$currentItemCount = count($itemsIds);

}

echo $currentItemCount;
`

and in my app\design\frontend\Sample\theme-frontend-shop\Magento_Catalog\layout\catalog_product_view.xml I have added
<referenceBlock name="product.info.addtocart" class="Magento\Checkout\Block\Cart" before="-" template="Blumeidealnew_shop::product/view/form.phtml" cacheable="false" />

But this is not working properly when full page cache is enabled.

Need help to fix this issue.

You should never user ObjectManager in M2 unless you are writing a Symfany a lá php bin/magento script..

Then how can I get cart item count from a custom theme html page?

You could use a Controller and put the class in the constructor, or if it's a normal theme just in the block class contructor you are using
