Glad to say i’ve solved it myself.

In stead of pulling post_categories, i had to pull the terms. Since its in a custom post / taxoomy, I had to pull the object_terms in stead of the post terms.

So I’ve got my terms via $term = get_term_by('id', $dateCatId, 'gemeente'); , gemeente being my taxonomy.

Next problem was that my wp_get_object_terms read the ID as a string and created a new category with the id as slug. Thats why i pull the ID back out on the term like this:
wp_set_object_terms($post_id, $term->term_id, 'gemeente');

Hope i’ve helpen someone with this, and also, if anyone has a better alternative, glad to hear it!

function my_acf_save_post($post_id) {

    // bail early if no ACF data
    if (empty($_POST['acf'])) {
        return;
    }

    //array of category id's
    $categoryIds = array();

    //value of 'date' field is the cat_id
    $dateCatId = get_field('organisatie');//http://www.advancedcustomfields.com/resources/get_field/
    array_push($categoryIds, $dateCatId);

    $term = get_term_by('id', $dateCatId, 'gemeente');

    wp_set_object_terms($post_id, $term->term_id, 'gemeente');
}

// run before ACF saves the $_POST['acf'] data
//add_action('acf/save_post', 'my_acf_save_post', 1);

// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 20);
