Can't find value in select2 ajax loading in yii2 - php

Question

I use select2 ajax loading. I get the code from this link: http://demos.krajee.com/widget-details/select2. When I enter words into field, it display all data/value, but it can't automatic select data/value according to words that I enter into field. So, my select2 always select the first data/value and display all value. What's the problem? These are the codes:
_form.php
$url = Url::to(['/paket/jsonlist']);
$cityDesc = empty($model->no_induk) ? '' : Penerima::findOne($model->no_induk)->nama;
echo $form->field($model, 'no_induk')->widget(Select2::classname(), [
'initValueText' => $cityDesc, // set the initial display text
'options' => ['placeholder' => 'Search for a city ...'],
'pluginOptions' => [
'allowClear' => true,
'minimumInputLength' => 1,
'language' => [
'errorLoading' => new JsExpression("function () { return 'Waiting for results...'; }"),
],
'ajax' => [
'url' => $url,
'dataType' => 'json',
'data' => new JsExpression('function(params) { return {q:params.term}; }')
],
'escapeMarkup' => new JsExpression('function (markup) { return markup; }'),
'templateResult' => new JsExpression('function(no_induk) { return no_induk.text; }'),
'templateSelection' => new JsExpression('function (no_induk) { return no_induk.id; }'),
],
]);
my controller:
public function actionJsonlist($q = NULL, $id = NULL)
{
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
$out = ['results' => ['id' => '', 'text' => '']];
if(!is_null($q))
{
$query = new \yii\db\Query;
$mainQuery = $query->select('no_induk AS id, nama AS text')
->from('penerima')
->limit(20);
$command = $mainQuery->createCommand();
$data = $command->queryAll();
$out['results'] = array_values($data);
}
elseif ($id > NULL)
{
$out['results'] = ['id' => $id, 'text' => \frontend\models\Penerima::find($id)->nama];
}
return $out;
}

Could be you use the attribute name and not the vars
echo $form->field($model, 'no_induk')->widget(Select2::classname(), [
'initValueText' =>'cityDesc', // set the initial display text
or
echo $form->field($model, 'no_induk')->widget(Select2::classname(), [
'initValueText' =>$model->cityDesc, // set the initial display text
