Woocommerce trigger the "order review" update in checkout page

I’m using the Woocommerce Advanced Shipping plugin by Jeroen Sormani for the shipping methods and the WooCommerce Pay for Payment plugin by Karolína Vyskočilová to add a €5 fixed fee to the “cash on delivery” payment method.

Using the Advanced Shipping Plugin, I also created a general rule called “Local pickup” to be always visible to the customers. Then I needed to hide the “cash on delivery” payment method when the “local pickup” shipping option is selected. To achieve this I had to add some code to my functions.php file in order to identify the specific local pickup rule inside the advanced shipping rules:

function my_custom_available_payment_gateways( $gateways ) {
    $chosen_shipping_rates = WC()->session->get( 'chosen_shipping_methods' );
    // When 'local pickup' (rule id 21828) has been chosen as shipping rate
    if ( in_array( '21828', $chosen_shipping_rates ) ) :
        // Unset 'cash on delivery'
        unset( $gateways['cod'] );
    endif;
return $gateways;
}
add_filter( 'woocommerce_available_payment_gateways', 'my_custom_available_payment_gateways' );

Here is my problem: In the checkout page, when I switch to “local pickup”, the “cash on delivery” option disappears as said before, but the €5 fee in the order review table stays there. I have to manually switch the payment method again (i.e. from bank transfer to credit card) in order to make the fee disappear.

I need to find some solution to trigger the order review update/refresh when the local pickup is selected.

I tried inserting the following script in the checkout page with no success

function woocommerce_add_update_cart() {
    // Only on checkout page
    if( ! is_checkout() ) return;
    ?>
    <script type="text/javascript">
    jQuery(document.body).trigger("update_checkout");
    </script>
    <?php
}
add_action( 'wp_footer', 'woocommerce_add_update_cart' );

    I managed to solve my problem. The $('body').trigger('update_checkout'); function suggested by itzmekhokan is not working in order to remove the extra fee from the updated order review. I had to simulate the click on one of the payment methods radio buttons to trigger the checkout update.

    For the checkout page:

    function woocommerce_add_update_checkout() {
    // Only on checkout page
    if( ! is_checkout() ) return;
    ?>
    <script type="text/javascript">
    (function($){
        $('form.checkout').on( 'change', 'input[name^="shipping_method"]', function() {
        document.getElementById("payment_method_bacs").checked = true;
        });
    })(jQuery);
    </script>
    <?php
}
add_action( 'wp_footer', 'woocommerce_add_update_checkout' );

    For the cart page summary:

    function reset_payment_method() {
    // Only on cart page
    if( ! is_cart() ) return;
    $payment_method = WC()->session->get( 'chosen_payment_method' );
    if ( $payment_method = 'cod' ) :
        WC()->session->set( 'chosen_payment_method', 'bacs' );
    endif;
}
add_filter( 'woocommerce_before_shipping_calculator', 'reset_payment_method' );

    You can add the follows code snippet – 

    function refresh_checkout_on_payment_methods_change(){
    ?>
    <script type="text/javascript">
        (function($){
            $( 'form.checkout' ).on( 'change', 'input[name^="shipping_method"]', function() { 
                $('body').trigger('update_checkout');
            });
        })(jQuery);
    </script>
    <?php
}

add_action( 'woocommerce_review_order_before_payment', 'refresh_checkout_on_payment_methods_change' );
