Custom Variable Product Type

Hi support team,
I registered a custom product type which extends WC_Product_Variable class.

In the backend, I can create custom product and set its attributes and variations.

But on the front-end, I am getting

This product is currently out of stock and unavailable.

Here is my class:

<?php

class KNL_SHOP_WC_GIFTCARD_PROD_TYPE extends WC_Product_Variable {
	public function __construct( $product = 0 ) {
		parent::__construct( $product );
	}

	public function get_type() {
		return 'knl_shop_giftcard';
	}

	/*public function is_purchasable() {
		return apply_filters( 'woocommerce_is_purchasable', true, $this );
	}*/

	public function knl_shop_giftcard_add_to_cart() {
		global $product;

		$get_variations = count( $product->get_children() ) <= apply_filters( 'woocommerce_ajax_variation_threshold', 30, $product );
		
		wc_get_template('single-product/add-to-cart/giftcard.php',
			$args = array(
					'available_variations' => $get_variations ? $product->get_available_variations() : false,
					'attributes'           => $product->get_variation_attributes(),
					'selected_attributes'  => $product->get_default_attributes(),
			),
			$template_path = '',
			KNL_SHOP_PATH . '/woocommerce/'
		);
	}
}

For template, I copied and renamed variable.php template.

Any help will be appreciated.
