Yii2 Pjax reloads entire page on second form submit - php

Question

I cannot seem to figure out why pjax reloads the page on the second form submission. It works exactly as intended on the first form submission pulling from this url /site/profile?UserSearch%5Bsearchstring%5D=mi&_pjax=%23form-pjax, however, after that first one it loses the ending of the url /site/profile?UserSearch%5Bsearchstring%5D=m. I checked the actual html code and the form is retaining the data-ajax attribute. I tried increasing the timeout as had been suggested when pjax is reloading the entire page, but that did not change anything.
Below is the code from my view
<?php Pjax::begin(['timeout' => 5000, 'id' => 'form-pjax']); ?>
<?php $form = ActiveForm::begin([
'method' => 'get',
'action' => Url::to(['site/profile']),
'options' => ['data-pjax' => true ],
]); ?>
<?= $form->field($searchModel, 'searchstring', [
'template' => '<div class="input-group">{input}<span class="input-group-btn">' .
Html::submitButton('Search', ['class' => 'btn btn-default']) .
'</span></div>',
])->textInput(['placeholder' => 'Find friends by username or email']);
?>
<?php ActiveForm::end(); ?>
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
'username',
[
'label' => 'View Profile',
'format' => 'raw',
'value'=>function ($data) {
return Html::a(Html::encode("View Profile"),'/site/redirectprofile/'.$data->id);
},
],
[
'label' => 'Follow',
'format' => 'raw',
'value'=>function ($data) {
return Html::a(Html::encode(Follow::find()->where(['user_id' => $data->id, 'follower_id' => Yii::$app->user->Id])->exists() ? 'Unfollow' : 'Follow'),'/site/follow/'.$data->id.'/'.$data->username);
},
],
],
'summary'=>'',
]); ?>
<?php Pjax::end(); ?>

You must call needed javascript triggers/functions after every pjax reload like:
$('#form-pjax').on('pjax:success', function() {
/*call Your functions here, or copy from your generated page js code,
that bind event to pjax form,
at end of generated html You should have something like: */
jQuery(document).on('submit', "#form-pjax form[data-pjax]", function (event) {
jQuery.pjax.submit(event, '#form-pjax', {"push":true,"replace":false,"timeout":000,"scrollTo":false});
});
});
This is not yii2 issue, it's how javascript works, when You add dynamically content it's needed to bind triggers/events for every added element.
