PJAX in ListView

Hello. Please help solve the problem with PJAX, I have a form and ListView above, so, after the ListView is updated, focus on the input field disappears, and it turns out that as long as the user enters a message when you update the field focus ListView disappears and the user must press re-press golf continue writing.

<?php echo Html::beginForm(); ?>

        <div class = "form-horizontal" role = "form" id = "form_message">


            <div class = "input-group">																				

                <?php echo Html::activeTextInput($form_model, 'message', ['class' => 'form-control', 'value'=>'']); ?>

                <?php echo Html::activeHiddenInput($form_model, 'group_id', ['value'=>$group_model->group_id]); ?>

                <?php echo Html::activeHiddenInput($form_model, 'to_user', ['value'=>Yii::$app->user->id == $group_model->user_to ? $group_model->user_from : $group_model->user_to]); ?>

                <span class="input-group-btn">

                    <?php echo Html::submitButton('Отправить', ['class' => 'btn btn-default']); ?>

                </span>																																																																																						

            </div>

        </div>

        <?php echo Html::endForm(); ?>


        <?php echo Html::error($form_model, 'message'); ?>


        <hr />


        <?php

        yii\widgets\Pjax::begin(['options' => ['id'=>123, 'timeout'=>3000]]);

        echo ListView::widget([

            'dataProvider' => $dataProvider,

            'itemView' => '_message',

            'layout' => "{items}\n{pager}"

        ]);

        yii\widgets\Pjax::end();


        $this->registerJs("

    function updateMessage(){

        $.pjax.reload({container: '#123'});

    }

    

    $(document).ready(function(){

        setInterval(updateMessage, 3000);

    });

");

        ?>
