Why is validator js not registering?

Question

Yii

Good afternoon.

the form:

<?php
use frontend\widgets\ActiveForm;
use usni\library\utils\Html;

use common\modules\order\models\Order;
use cart\models\BillingInfoEditForm;
use cart\models\DeliveryInfoEditForm;
use cart\models\DeliveryOptionsEditForm;
use cart\models\PaymentMethodEditForm;

                Modal::begin([
                    'header' => '<h2>' . Ecocom::t('cart', 'One click buy') . '</h2>',
                    'toggleButton' => [
                        'label' => Ecocom::t('cart', 'One click buy'),
                        'tag' => 'button',
                        'class' => 'btn btn-success',
                    ]
                ]);
                $form = ActiveForm::begin([
                    'id' => 'oneclick-form',
                    'caption' => $this->title,
                    'enableAjaxValidation' => true,

                ]);

                $modelOrder = new Order();
                $modelBiling = new BillingInfoEditForm();
                $modelDeliverInfo = new DeliveryInfoEditForm();
                $modelDeliverOptions = new DeliveryOptionsEditForm();
                $modelPayment = new PaymentMethodEditForm();
                echo $this->render('@common/modules/cart/views/_oneclickbuy',
                    [
                        'form' => $form,
                        'modelOrder' => $modelOrder,
                        'modelBiling' => $modelBiling,
                        'modelDeliverInfo' => $modelDeliverInfo,
                        'modelDeliverOptions' => $modelDeliverOptions,
                        'modelPayment' => $modelPayment
                    ]);
                echo Html::submitButton(Ecocom::t('application', 'Continue'), ['id' => 'oneclick-but-sub', 'class' => 'btn btn-success', 'name' => 'submit-order']);

                ActiveForm::end();
                Modal::end();

Inputs:

$model = [];
$model['order'] = $modelOrder;

Model example:

<?php
/**
 * --
 * --
 */
namespace cart\models;

use yii\base\Model;
use usni\Ecocom;
use usni\library\validators\EmailValidator;
use usni\library\modules\users\models\Address;
use usni\library\modules\users\models\Person;
use usni\library\utils\ArrayUtil;
use usni\library\modules\users\utils\UserUtil;
use common\modules\order\models\OrderAddressDetails;
/**
 * BillingInfoEditForm class file
 * 
 * @package cart\models
 */
class BillingInfoEditForm extends Model
{
    //Person fields
    public $email;
    public $firstname;
    public $lastname;
    public $mobilephone;
    public $officephone;
    //Address fields
    public $address1;
    public $city;
    public $country;
    public $postal_code;
    public $address2;
    public $state;

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return array(
            //Person rules
            [['firstname', 'lastname'],         'string', 'max' => 32],
            ['email',                           'required'],
            ['email',                           EmailValidator::className()],
            ['mobilephone',                     'number'],
            //Address rules
            [['address1', 'city', 'country', 'postal_code', 'firstname', 'lastname', 'mobilephone'], 'required'],
            [['address1', 'address2'],          'string', 'max' => 128],
      [['city', 'state', 'country'],      'string', 'max' => 64],
      [['firstname', 'lastname', 'address1', 'city', 'country', 'postal_code', 'state', 'address2', 'email', 'officephone', 'mobilephone'],  'safe'],
        );
    }

    /**
     * @inheritdoc
     */
    public function attributeHints()
    {
        $person     = new Person();
        $address    = new Address();
        return ArrayUtil::merge($person->attributeHints(), $address->attributeHints());
    }
}

Problem: there is no js code that handles errors on the client side.
