I have created quick order functionality on custom page layout .
Process like below:
customer find product in textbox and display matching products in autocomplete.In autocomplete result displays product-name,image and add to cart button.when I click add-to-cart button ,ajax call in custom created controller and I created code for programmatically add-to-cart product.Product add to cart successfully via my ajax code but mincart not render on top but when I refresh page then it displays products in minicart.
