FormAPI doesn’t execute

Code:

PHP:

            $api = $this->plugin->getServer()->getPluginManager()->getPlugin("FormAPI");
            $form = $api->createSimpleForm(function (Player $player, $data){
                $result = $data[0];
                if($result === null){
                }
                switch($result[0]){
                    case 1:
                    $player->sendMessage("test");
                    break;
                }
            });

            $form->setTitle("Test SOCKK");
            $form->addButton("Butt", 1);
            $form->sendToPlayer($player);

 

PHP:


    function onCommand(CommandSender $sender, Command $cmd, string $label, array $args):
        bool
            {
            switch ($cmd->getName())
                {
            case "buycraftui":
                if ($sender instanceof Player)
                    {
                    $api = $this->getServer()->getPluginManager()->getPlugin("FormAPI");
                    if ($api === null || $api->isDisabled())
                        {
                        }

                    $form = $api->createSimpleForm(
                    function (Player $sender, array $data)
                        {
                        $result = $data[0];
                        if ($result === null)
                            {
                            }

                        switch ($result)
                            {
                        case 0:
                            break;

                        case 1:
                            $this->cashForm($sender);
                            break;
                            }
                        });
                    $form->setTitle(TextFormat::BOLD . "buycraft");
                    $form->setContent("Your cart: " . TextFormat::GOLD . $cart);
                    $form->addButton("");
                    $form->addButton(TextFormat::BOLD . "cash' );
                    $form->sendToPlayer($sender);
                    }
                  else
                    {
                    $sender->sendMessage(TextFormat::RED . "Use this Command in-game.");
                    return true;
                    }

                break;
                }

            return true;
            }
