u are a legend CHEWX , thanks a lot.

Am using this code if anyone want it and it works :

add_filter('woocommerce_product_single_add_to_cart_text', 'woo_custom_cart_button_text',1);
function woo_custom_cart_button_text() {
return __('Your Text Button', 'woocommerce');
}

Thanks to the original code and previous comments with updates, I was able to put something together that is working. This is the only thing that worked for me:

add_filter( 'woocommerce_product_single_add_to_cart_text', 'custom_single_add_to_cart_text' );
function custom_single_add_to_cart_text() {
	return 'Add To Cart';
}
