Replacing Price Range of Variation in Woocommerce 3.8 - php

Question

Been using this code to replace woocommerce variation prices but after updating to Woocommerce 3.8, this code stopped working.
I have used the following code in the theme's function.php file thanks to : LoicTheAztec
Code is from original post here
Thanks in advance!
// Utility function to get the default variation (if it exist)
function get_default_variation( $product ){
$attributes_count = count($product->get_variation_attributes());
$default_attributes = $product->get_default_attributes();
// If no default variation exist we exit
if( $attributes_count != count($default_attributes) )
return false;
// Loop through available variations
foreach( $product->get_available_variations() as $variation ){
$found = true;
// Loop through variation attributes
foreach( $variation['attributes'] as $key => $value ){
$taxonomy = str_replace( 'attribute_', '', $key );
// Searching for a matching variation as default
if( isset($default_attributes[$taxonomy]) && $default_attributes[$taxonomy] != $value ){
$found = false;
break;
}
}
// If we get the default variation
if( $found ) {
$default_variaton = $variation;
break;
}
// If not we continue
else {
continue;
}
}
return isset($default_variaton) ? $default_variaton : false;
}
add_action( 'woocommerce_before_single_product', 'move_variations_single_price', 1 );
function move_variations_single_price(){
global $product, $post;
if ( $product->is_type( 'variable' ) ) {
// removing the variations price for variable products
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );
// Change location and inserting back the variations price
add_action( 'woocommerce_single_product_summary', 'replace_variation_single_price', 10 );
}
}
function replace_variation_single_price(){
global $product;
// Main Price
$prices = array( $product->get_variation_price( 'min', true ), $product->get_variation_price( 'max', true ) );
$active_price = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );
// Sale Price
$prices = array( $product->get_variation_regular_price( 'min', true ), $product->get_variation_regular_price( 'max', true ) );
sort( $prices );
$regular_price = $prices[0] !== $prices[1] ? sprintf( __( 'From: %1$s', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );
if ( $active_price !== $regular_price && $product->is_on_sale() ) {
$price = '<del>' . $regular_price . $product->get_price_suffix() . '</del> <ins>' . $active_price . $product->get_price_suffix() . '</ins>';
} else {
$price = $regular_price;
}
// When a default variation is set for the variable product
if( get_default_variation( $product ) ) {
$default_variaton = get_default_variation( $product );
if( ! empty($default_variaton['price_html']) ){
$price_html = $default_variaton['price_html'];
} else {
if ( ! $product->is_on_sale() )
$price_html = $price = wc_price($default_variaton['display_price']);
else
$price_html = $price;
}
$availiability = $default_variaton['availability_html'];
} else {
$price_html = $price;
$availiability = '';

The problem is the jQuery targeting .Blur which was removed in WooCommerce 3.8.
Solution:
Replace line:
$('select').blur( function(){
With -
$('input.variation_id').change( function(){
