Adding token to the url of the Update action Yii2 - yii2-advanced-app

Question

I am wondering where can I add the token parameter to the url in the backend? What my url looks now at this moment is www.domain.com/admin/brand/update?id=26 and I simply want to add one token in the end to prevent caching like this www.domain.com/admin/brand/update?id=26&token=23782173812. But now at this moment I realized that I don't know where is that url constructed. This is my controller action:
public function actionUpdate($id)
{
$model = $this->findModel($id, false);
$settings = new Settings;
if ($model->load(Yii::$app->request->post())) {
$languages = Lang::find()->all();
foreach ($languages as $language) {
if ($language->default != 1) {
$title = 'title_' . $language->url;
$varTitle = Yii::$app->OutData->sanitize($model->$title);
$model->$title = $varTitle;
$description = 'description_' . $language->url;
$varDescription = Yii::$app->OutData->sanitize($model->$description);
$model->$description = $varDescription;
} else {
$model->title = Yii::$app->OutData->sanitize($model->title);
$model->description = Yii::$app->OutData->sanitize($model->description);
}
}
$model->link = Yii::$app->OutData->sanitize($model->link);
if ($model->save()) {
$model = $this->findModel($model->id, true);
foreach ($languages as $language) {
if ($language->default != 1) {
$urlName = 'url_' . $language->url;
$model->$urlName = MakeURL::parseUrlGoogle($model->$urlName, $model->id);
} else {
$model->url = MakeURL::parseUrlGoogle($model->url, $model->id);
}
}
$model->update();
$model->setImageFolder();
$model->imageFiles = UploadedFile::getInstances($model, 'imageFiles');
if (isset($model->imageFiles) and count($model->imageFiles) > 0) {
foreach ($model->imageFiles as $key => $file) {
$file->saveAs(Yii::getAlias('#frontend/web') . '/brands_images/'.$model->getImageFolderName().'/brand_' . $model->id . '_' . ($key + 1) . '.' . $file->extension);
$pic = Yii::getAlias('#frontend/web') . '/brands_images/'.$model->getImageFolderName().'/brand_' . $model->id . '_' . ($key + 1) . '.' . $file->extension;
/* $settings->compress($pic, $pic, 90);*/
}
}
return $this->redirect(['index']);
} else {
return $this->render('update', [
'model' => $model,
]);
}
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
And my form if it is needed:

use kartik\file\FileInput;

$_SESSION['KCFINDER'] = array(
'disabled' => false,
'uploadURL' => "/media",
'uploadDir' => Yii::getAlias('#frontend/web') . "/media/",
);
