Handheld menu Search doesn’t work

Dear…

I’ve been try to add snippet to change the custom order of handheld menu, but when the search callback i’ve some problem.. This is the code :

add_filter( 'storefront_handheld_footer_bar_links', 'jk_remove_handheld_footer_links' );
function jk_remove_handheld_footer_links( $links ) {
	unset( $links['my-account'] );
	unset( $links['search'] );
	unset( $links['cart'] );

	return $links;
}

add_filter( 'storefront_handheld_footer_bar_links', 'jk_add_home_link' );
function jk_add_home_link( $links ) {

	$new_links = array(
		'home' => array(
			'priority' => 20,
			'callback' => 'jk_home_link',
		),
		'search' => array(
			'priority' => 30,
			'callback' => 'storefront_handheld_footer_bar_search_link',
		),
		'my-account' => array(
			'priority' => 40,
			'callback' => 'storefront_handheld_footer_bar_account_link',
		),
	);

	$links = array_merge( $new_links, $links );

	return $links;
}

function jk_home_link() {
	echo '<a href="' . esc_url( home_url( '/' ) ) . '">' . __( 'Home' ) . '</a>';
}
