Refresh shipping rates on city select field - wordpress

Question

I am trying to update/refresh the shipping rates on city change, so far I have managed to do so only by refreshing the page manually.
add_action( 'woocommerce_package_rates', 'check_minimum_and_city', 10, 2 );
function check_minimum_and_city($rates, $package){
$selected_city = WC()->checkout->get_value('billing_city');
$price_thirty = array('bat-yam','hulon','azur','tel-aviv-yafo','givatayim','ramat-gan','bnei-brak','rishon-letzion','netaim','yavne','kfar-nagid','galiya','ben-zakai','beit-gamliel');
$price_fifty = array('einot','gan-shlomo','beit-oved','aseret','givat-brener','irus','misgav-dov','givton','kerem-yavne','beit-raban','rehovot','beit-elezri','beit-hanan','kvuzat-yavne','kfar-bilu','bnei-darom','nir-galim','kiryat-ekron','gedera','nes-tziona','kanot','gan-darom','netayim','mishmar-hashiva','gan-sorek','beit-dagan','ganot','beit-hanan-irus','hemed');
$price_sixty = array('savion','ganei-tikva','or-yehuda','kiryat-ono','yehud','petah-tikva','ramat-hasharon','herzliya','kfar-shmariyahu','rishpon','raanana','kfar-saba','tsafria','beer-yaakov','netser-sireni','nir-tzvi','ramla','matsliax','bnaya','kfar-aviv');
if(WC()->session->get( 'chosen_shipping_methods' )[0] == 'local_pickup:13'){
$minimum = 0;
}else{
$minimum_thirty = 100;
$minimum_fifty = 150;
$minimum_sixty = 200;
if(in_array($selected_city, $price_thirty)){
unset( $rates['flat_rate:18']);
unset( $rates['flat_rate:19']);
if(WC()->cart->subtotal < $minimum_thirty){
throw new Exception(
sprintf( 'סכום ההזמנה הנוכחית שלך עומד על %s, מינימום הזמנה לפני משלוח הינו %s.' ,
wc_price( WC()->cart->subtotal ),
wc_price( $minimum_thirty )
)
);
}
}elseif(in_array($selected_city, $price_fifty)){
unset( $rates['flat_rate:9']);
unset( $rates['flat_rate:19']);
if(WC()->cart->subtotal < $minimum_fifty){
throw new Exception(
sprintf( 'סכום ההזמנה הנוכחית שלך עומד על %s, מינימום הזמנה לפני משלוח הינו %s.' ,
wc_price( WC()->cart->subtotal ),
wc_price( $minimum_fifty )
)
);
}
}elseif(in_array($selected_city, $price_sixty)){
unset( $rates['flat_rate:9']);
unset( $rates['flat_rate:18']);
if(WC()->cart->subtotal < $minimum_sixty){
throw new Exception(
sprintf( 'סכום ההזמנה הנוכחית שלך עומד על %s, מינימום הזמנה לפני משלוח הינו %s.' ,
wc_price( WC()->cart->subtotal ),
wc_price( $minimum_sixty )
)
);
}
}
return $rates;
}
}
When I select a city field (dropdown custom list) I get the shipping cost I have made through the woocommerce settings but when I change it it does not update the rates.
add_filter( 'woocommerce_checkout_fields', 'city_dropdown_field' );
function city_dropdown_field( $fields ) {
$city_args = wp_parse_args( array(
'type' => 'select',
'options' => array(

), $fields['shipping']['shipping_city'] );
$fields['shipping']['shipping_city'] = $city_args;
$fields['billing']['billing_city'] = $city_args;
return $fields;
}
Tried using this jQuery but nothing does the work
add_action( 'wp_footer', 'checkout_shipping_city_refresh_display' );
function checkout_shipping_city_refresh_display() {
// On checkout
if ( is_checkout() && ! is_wc_endpoint_url() ) :
?><script type="text/javascript">
jQuery( function($){
// Shipping fias code change & input events
$(document.body).on( 'change', 'select[name=billing_city]', function() {
console.log($(this).val());
});
});
</script>
<?php
endif;
}
Help is appreciated. :-)

I have Managed to resolve the issue and here is my solution, the answer was in corrected AJAX call and changing from multiple shipping rates to one and changing the rate by code.
add_action('woocommerce_checkout_update_order_review', 'refresh_shipping_methods', 10, 1 );
function refresh_shipping_methods( $post_data ){
WC()->cart->calculate_shipping();
}
add_action( 'wp_footer', 'checkout_shipping_city_refresh_display' );
function checkout_shipping_city_refresh_display() {
// On checkout
if ( is_checkout() && ! is_wc_endpoint_url() ) :
?><script type="text/javascript">
jQuery(document).on('change', 'select[name=billing_city]', function(){
var requested_city = jQuery(this).val();
ajaxurl = '<?php echo admin_url( 'admin-ajax.php' ) ?>'; // get ajaxurl
var data = {
'action': 'get_and_set_shipping_rate',
'city': requested_city
};
jQuery.ajax({
type: "POST",
url: ajaxurl, // this will point to admin-ajax.php
data: data,
async: false,
success: function (response) {
console.log(response);
setTimeout(function (){
jQuery('.shipping_method:checked').trigger('change');
});
}
});
});
</script>
<?php
endif;
}
function get_and_set_shipping_rate(){
$shipping_city = $_POST['city'];
$shipping_cost = get_shipping_cost_by_city($shipping_city);
setcookie('shipping_city_cost', $shipping_cost, time() + (86400 * 30), '/');
$_COOKIE['shipping_city_cost'] = $shipping_cost;
echo $shipping_cost;
wp_die();
}
add_action( 'wp_ajax_get_and_set_shipping_rate', 'get_and_set_shipping_rate' );
add_action( 'wp_ajax_nopriv_get_and_set_shipping_rate', 'get_and_set_shipping_rate' );
