yii2-dynamicform. I can't update - yii2

Question

I want to use dynamic form widget (wbraganca).
I tried it using the tutorial by 'doingItEasy' channel & also by github.
I can create and delete,but I can't update.:
Controller:
public function actionUpdate($id) {
$model = $this->findModel($id);
$modelsDentalist = $model->dentalists;
if ($model->load(Yii::$app->request->post()) && $model->save()) {
$oldIDs = ArrayHelper::map($modelsDentalist, 'id', 'id');
$modelsDentalist = Model::createMultiple(Dentalist::classname(), $modelsDentalist);
Model::loadMultiple($modelsDentalist, Yii::$app->request->post());
$deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsDentalist, 'id', 'id')));
$valid = $model->validate();
$valid = Model::validateMultiple($modelsDentalist) && $valid;
if ($valid) {
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($flag = $model->save(false)) {
if (!empty($deletedIDs)) {
CalItem::deleteAll(['id' => $deletedIDs]);
}
foreach ($modelsDentalist as $modelDentalist) {
$modelDentalist->denta_id = $model->denta_id;
if (!($flag = $modelDentalist->save(false))) {
$transaction->rollBack();
break;
}
}
}
if ($flag) {
$transaction->commit();
return $this->redirect(['index']);
}
} catch (Exception $e) {
$transaction->rollBack();
}
}
} else {
return $this->render('update', [
'model' => $model,
'modelsDentalist' => (empty($modelsDentalist)) ? [new Dentalist] : $modelsDentalist
]);
}
}

I can't update. Error:Getting unknown property: app\models\Dentalist::id

i think you can edit below line in Controller:
$oldIDs = ArrayHelper::map($modelsDentalist, 'denta_id', 'denta_id');
$modelsDentalist = Model::createMultiple(Dentalist::classname(), $modelsDentalist);
Model::loadMultiple($modelsDentalist, Yii::$app->request->post());
$deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsDentalist, 'denta_id', 'denta_id')));
and also edit line in _form:
echo Html::activeHiddenInput($modelDentalist, "[{$i}]denta_id");
