Form update using modal in yii2 strange - php

Question

I've tried for created form update using modal in yii2. The problem is every I change one field with the other value, the result form update with modal closed and redirect to index. And message update can't display in index. I don't know why, maybe wrong in code controller.
Code actionUpdate in controller
public function actionUpdate($id)
{
$model = CalonKeluargaAsuh::findOne($id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
Yii::$app->session->setFlash('success', 'Data berhasil diubah!');
return $this->redirect(['index']);
return $this->refresh();
} else {
if (Yii::$app->request->isAjax) {
return $this->renderAjax('update', ['model' => $model]);
}
else{
return $this->render('update', ['model' => $model]);
}
}
}
Code form in view
<?php
use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
use yii\widgets\Pjax;
?>
<h2 align="center">Ubah Data Calon Keluarga Asuh</h2>
<?php
echo "&nbsp";
echo "&nbsp";
?>
<?php $form = ActiveForm::begin(['layout' => 'horizontal', 'enableAjaxValidation' => true,
'id' => 'update-form',
]); ?>
<?= $form->field($model, 'kode_calon_keluarga_asuh')->textInput(['readOnly' => true, 'style' => 'width:350px' ]) ?>
<?= $form->field($model, 'nama')->textInput(['style' => 'width:350px']) ?>
<?= $form->field($model, 'jenis_kelamin')->dropDownList(['Laki-laki' => 'Laki-laki', 'Perempuan' => 'Perempuan'],
['prompt'=>'--Pilih--', 'style' => 'width:350px']) ?>

<?= $form->field($model, 'alamat')->textArea(['rows' => 3, 'style' => 'width:350px']) ?>

<div class="form-group">
