Modal registration not working?

Question

Yii

Hello comrades.
When in the modal window in the form I enter the mail and password (then when the mail is entered, the data already appears in the tables) and I click to register, it says to me that the soap is already taken by the
controller

public function actionSignUp()
    {
        $emailActivation = Yii::$app->params['emailActivation'];
        $model = $emailActivation ? new Signup(['scenario' => 'emailActivation']) : new Signup();

        if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post()) && $model->validate()) {

            if ($user = $model->signup()) {
                if ($user->status === User::STATUS_ACTIVE) {
                    if (Yii::$app->getUser()->login($user)) {
                        return $this->goHome();
                    }
                } else {
                    if ($model->sendActivationEmail($user)) {
                        Yii::$app->session->setFlash('success', 'Письмо с активацией отправлено на емайл <strong>' . Html::encode($user->email) . '</strong> (проверьте папку спам).');
                    } else {
                        Yii::$app->session->setFlash('error', 'Ошибка. Письмо не отправлено.');
                        Yii::error('Ошибка отправки письма.');
                    }
                }
            } else {
                Yii::$app->session->setFlash('error', 'Возникла ошибка при регистрации.');
                Yii::error('Ошибка при регистрации');
                Yii::$app->response->format = Response::FORMAT_JSON;
                return ActiveForm::validate($model);
//                Yii::$app->session->setFlash('error', 'Возникла ошибка при регистрации.');
//                Yii::error('Ошибка при регистрации');
//                return $this->refresh();
            }
        }

        return $this->renderAjax('sign-up', ['model' => $model]);
    }

It works for you return $this->renderAjaxSo look in the controller why it comes to it. And I understand you ajax is waiting for errors and not renderAjax
