WooCommerce custom bulk action

I have succesfully created a custom bulk action, but the problem is, if I have several orders, it will only work for the first order. Lets say I have orders numbers #1, #2 and #3, the custom bulk action will only work for the order number #1.

Here is the sample of the code I use:

public function __construct () {
    add_action( 'admin_footer-edit.php', array( $this, 'wb_my_action_order_status' ) );
    add_action( 'load-edit.php', array( $this, 'my_action_custom_action' ) );
}

public function wb_my_action_order_status() {
    global $post_type;
    if($post_type == 'shop_order') {
        ?>
        <script type="text/javascript">
            jQuery(document).ready(function() {
                jQuery('<option>').val('my_action').text('<?php _e('my_action', 'wb-my_action')?>').appendTo("select[name='action']");
                jQuery('<option>').val('my_action').text('<?php _e('my_action', 'wb-my_action')?>').appendTo("select[name='action2']");
            });
        </script>
        <?php
    }

}


public function my_action_custom_action() {

    global $typenow;
    $post_type = $typenow;

    if($post_type == 'shop_order') {
        $wp_list_table = _get_list_table('WP_Posts_List_Table');
        $action = $wp_list_table->current_action();

        $allowed_actions = array("my_action");

        if(!in_array($action, $allowed_actions)) return;

        if(isset($_REQUEST['post'])) {
            $orderids = array_map('intval', $_REQUEST['post']);
        }

            if(($action=='my_action') && ($order->status!='completed') ) {
                // Here do the action
            }

        }
}

So what am I missing here?
