You can add below code in ajax done function:

   require(
                    [
                        'jquery',
                        'Magento_Checkout/js/action/get-totals',
                        'Magento_Customer/js/customer-data'
                    ],
                    function ($, getTotalsAction, customerData) {
                        var sections = ['cart'];
                        customerData.reload(sections, true);
                        // The totals summary block reloading
                        var deferred = $.Deferred();
                        getTotalsAction([], deferred);
                      }
