Symfony: array for choice_attr not displaying for radio buttons

I've been trying to add HTML attributes to my radio buttons, but somehow it doesn't work. I'm using the built-in choice_attr option. In this case I do not want to use a callable, as the definition of choice_attr says that the value can be a callable, string or array. I'd like to use an array. Below is the code, what am I doing wrong?

    ->add('plan', ChoiceType::class, array(
        'choices' => array(
            'Basic' => 0,
            'Superb (+ €9)' => 1,
            'Super (+ €18)' => 2,
            'Rrah' => 3
        ),
        'expanded' => true,
        'data' => 0,
        'choice_attr' => [
            1 => ['data-price' => '0'],
            2 => ['data-price' => '9'],
            3 => ['data-price' => '18'],
            4 => ['data-price' => '0']
        ])
    )

choice_attr is used for HTML attributes bluppfisk. See the documentation:

http://symfony.com/doc/current/reference/forms/types/choice.html#choice-attr

The parameters of the choice_attr function needs to be one of $val, $key, $index, which represents the value, key and index of the 'choices' array that you use. So you could try:

'choice_attr' => function($val) {
    $price = 0;
    if ($val == 1) {
        $price = 9;
    }
    elseif ($val == 2) {
        $price = 18;
    }
    return ['data-price' => $price];
}
