How to make ActiveForm display validate?

Question

Yii

Good afternoon,
Folks, I'm making an Ajax form from a simple working form.
Without Ajax, everything works as it should, as soon as I make the Ajax form, validation stops working.
Zama form

$form = ActiveForm::begin([
    'id' => $model->formName(),
    'enableAjaxValidation' => true,
    'options' => [
        'enctype' => 'multipart/form-data',
        'class' => false,
    ],
    'errorCssClass' => 'hasError',
]);

Controller

public function actionTest(){
             $model = new MyPersonalForm('', $user,  Yii::$app->request->post('myPersonals'));

        if(Yii::$app->request->isPost && $model->validate()){
            if($model->saveMyPersonal()){

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

I check in the answer comes, the form being validated, how can I display it in the Ajax form? Thanks
I check without ajax and popup everything works like clockwork.
A validation error is assigned to a component in MyPersonalForm()

public function validate($attributes=null, $clearErrors=true){
        $return = parent::validate($attributes,$clearErrors);
        $skip_activity =false;

        foreach($this->user_personal as $ui)
        {
            if(!$ui->validate())
            {
                $this->addErrors($ui->getErrors());
                $return = false;
            }

            if($ui->is_active){
                $skip_activity =true;
            }
        }

        if(!$skip_activity){
            foreach($this->user_personal as $ui)
                $ui->addError('is_active','At least one activity must be selected or None.');
            $return = false;
        }

        return $return;
    }

This is how I always do it.
I create a trait in the core components (I use it everywhere where there is ajax validation)

trait AjaxValidationTrait
{
    /**
     * Performs ajax validation.
     *
     * @param Model $model
     *
     * @throws \yii\base\ExitException
     */
    protected function performAjaxValidation(Model $model)
    {
        if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
            Yii::$app->response->format = Response::FORMAT_JSON;
            echo json_encode(ActiveForm::validate($model));
            Yii::$app->end();
        }
    }
}

Then I connect this trait in the desired controller and load the model into it in the desired action.

class DefaultController extends BaseAdminController
{
    use AjaxValidationTrait;

   public function actionCreate()
    {
        $model = new Point();
        $this->performAjaxValidation($model);
       if ($model->validate()) {
        ....
        } else {
             return $this->render('create', [
                'model' => $model]
             );
        }
    }
}

Then, in the form itself, I disable client-side validation and enable ajax validation

<?php $form = ActiveForm::begin([
    'enableAjaxValidation'   => true,
    'enableClientValidation' => false,
]); ?>

1. You check if the ajax request is valid and what it returns. Why dig into the code when there is probably a specific error in debug. Maybe the routing is wrong.
2. Judging by your code in the controller, you do not return the validation result. What are you expecting? You receive a request, it is validated and saved if successful, or it returns a render of a certain view. And it should validate and return for example:
echo json_encode(ActiveForm::validate($model));
