WooCommerce Templates & How They Work? - php

Question

I've moved the Stock.PHP and Price.PHP files from Templates into my theme WooCommerce -> Single Product folder. Now, I've tried to move this line of code from Stock.PHP into Price.PHP:
<p class="stock <?php echo esc_attr( $class ); ?>"><?php echo wp_kses_post( $availability ); ?></p>
This is my Stock.PHP file now.
<?php
/**
* Single Product stock.
* #version 3.0.0
*/
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
?>
<!-- <p class="stock <?php echo esc_attr( $class ); ?>"><?php echo wp_kses_post( $availability ); ?></p> -->
And this is my Price.PHP file.
<?php
/**
* Single Product Price
* #version 3.0.0
*/
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly
}
global $product;
?>
<p class="price"><?php echo $product->get_price_html(); ?></p>
<p class="stock <?php echo esc_attr( $class ); ?>"><?php echo wp_kses_post( $availability ); ?></p>
But for no reason, the Stock is not getting the esc_attr value and the availability of the product. How come this paragraph does get the class and the availability inside the Stock file but not inside the Price file?
Thanks,
