How to redraw just one snippet in a component

Hi,

is it possible to redraw just one snippet defined in a component?

I tried using snippetArea in various places, but all I got was empty JSONs or errors.

Component

<?php

namespace App\Components;

class Random extends \Nette\Application\UI\Control{

    public function renderTest(){

        $this->template->a = \Nette\Utils\Random::generate(5);
        $this->template->b = \Nette\Utils\Random::generate(5);
        $this->template->c = \Nette\Utils\Random::generate(5);

        $this->template->render(__DIR__.'/test.latte');

    }

}

test.latte

{block content}

{snippet a}
    {$a} <a href="{plink :a!}" class="ajax">Refresh</a>
{/snippet}

{snippet b}
    {$b}  <a href="{plink :c!}" class="ajax">Refresh</a>
{/snippet}

{snippet c}
    {$c}  <a href="{plink :c!}" class="ajax">Refresh</a>
{/snippet}

Presenter

<?php

declare(strict_types=1);

namespace App\Presenters;

use Nette;


final class ComponentPresenter extends Nette\Application\UI\Presenter
{

    public function renderDefault(){

    }

    public function createComponentRandom(){
        return new \App\Components\Random;
    }


    public function handleA(){
		/*
		I tried different commands here

		$this->getComponent('random')->redrawControl('a');
		ends with the "Call to undefined method App\Components\Random::render()" error

		$this->redrawControl('name of snippet area defined in the presenter template');
		does nothing
		*/
        $this->redrawControl('a');
    }

    public function handleB(){
        $this->redrawControl('b');
    }

    public function handleC(){
        $this->redrawControl('c');
    }

}

default.latte

{block content}

{control random:test}
