How to properly use and override beforeSave method in Yii2 - overriding

Question

I have override the existing \yii\db\ActiveRecord with my own class. The method I've override is beforeSave(). I've read the documentation about the usage. But I found it's called twice when checking the record whether it is a new record or not.
This is my code:
class ActiveRecord extends \yii\db\ActiveRecord{
public $count = 0;
public function beforeSave($insert) {
print($this->count++); //i try to investigate it deeper using this "count" property
if(parent::beforeSave($insert)){
if($this->isNewRecord){
print("123"); //this printed out
if($this->hasAttribute('user_create')){
$this->user_create = \Yii::$app->user->identity->id;
}
if($this->hasAttribute('time_create')){
$this->time_create = new \yii\db\Expression('now()');
}
}
else{
print("456"); //and this is also
if($this->hasAttribute('user_upd')){
$this->user_upd = \Yii::$app->user->identity->id;
}
if($this->hasAttribute('time_upd')){
$this->time_upd = new \yii\db\Expression('now()');
}
}
return true;
}else{
return false;
}
}
}
and the output of the code when I do save a new record is as follow

I made a mistaken in the Controller Side, this is my Code
public function actionCreate() {
$model = new Grup();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
if ($model->save()) {
echo Json::encode(array('status' => 1));
} else {
echo Json::encode(array('status' => 0, 'message' => \kartik\widgets\ActiveForm::validate($model)));
}
} else {
return $this->renderAjax('create', [
'model' => $model,
]);
}
}
I shouldn't use $model->save() twice.
