In your view. Create an update button

echo 
Html::beginForm(['/model/update'], 'post',['id' => 'update-form']) .
'<input type="hidden" name="id" value="'.$model->id.'">
 <a href="javascript:{}" onclick="document.getElementById(\'update-form\').submit(); 
return false;">Update</a>'. 
Html::endForm();

Then in your controller

public function actionUpdate()
{
    if ( Yii::$app->request->post() ) {

        if ( isset (Yii::$app->request->post()['Model']['id']) ) {
            $id = Yii::$app->request->post()['Model']['id'];
        } else {
            $id = Yii::$app->request->post()['id'];
        }

        $model = $this->findModel($id);
    }

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(['index']);
    } else {
        return $this->render('update', [
            'model' => $model,
        ]);
    } 
}
