I’m trying to use infinitscroll extension of yii for my ListView but it’s not working if I submit a form using pjax or even ajax

this is my form




<?php 

$this->registerJs('

    $("#new_comment").on("pjax:end", function(e) {

			console.log ('.$postID.')

			$.pjax.defaults.timeout = false;

			$("#comments").load(" #comments");

			e.stopPropagation();

		});

   ');

?>


<div class="comments-form">


	<?php yii\widgets\Pjax::begin(['id' => 'new_comment']) ?>

    <?php $form = ActiveForm::begin(['id' => 'form-comment',

			'options' => ['data-pjax' => true, 'enctype' => 'multipart/form-data']]); ?>


    <?= $form->field($modelCmt, 'comment_Text')->textInput(['maxlength' => true, 'id' => 'commentText']) ?>


	<?= Html::input('hidden', 'post_id', $postID, ['id' => 'hdnInp']) ?>

	

    <div class="form-group text-right">

		<?= Html::submitButton(Yii::t('app', 'Add comment'), ['class' => 'btn btn-success']) ?>

    </div>


    <?php ActiveForm::end(); ?>

	

	<?php yii\widgets\Pjax::end() ?>

</div>

<?php Pjax::begin(['id' => 'comments']); ?>	


	<?= ListView::widget([

		'dataProvider' => $comments,

			'summary'=>'',

			'itemOptions' => ['class' => 'item'],

			'emptyText' => 'No Comments',

			'itemView' => function ($model, $key, $index, $widget) {

							return $this->render('pst-comment-table',['model' => $model]);
