yii2 two active form requires second click to submit - php

Question

I have two activeform in my view and one of them use pjax. And both of them requires second click to submit. I don't know what I am doing wrong. I search this problem in internet, but meet other cases of second click
<?php Pjax::begin(['id' => 'workers', "timeout" => 50000], ["options" => ["timeout" => 5000]]);?>
<?php
echo $this->render('_show', [
"model" => $searchModel,
"filials" => $filials,
"workers" => $workers,
"posts" => $posts,
]);
echo $this->render('_handle_form');
?>
<div class="row js-loader">
<div class="col-lg-12 col-md-12">
<div class="table-responsive">
<?=GridView::widget([
'dataProvider' => $dataProvider,
'emptyText' => 'Нет результатов',
'tableOptions' => ['class' => 'table table-hover table-claim table-claimadm', 'style' => 'font-weight:600;'],
'rowOptions' => ['class'=>'row-without-border row-open'],
'layout' => "{items}{pager}",
'columns' => [
[
...
]
]);?>
</div>
</div>
</div>
<?php Pjax::end();?>
<script>
window.onload = function () {
$(document).on('pjax:send', function (event) {
tbody = $('#' + event.target.id).find(".js-loader");
if (tbody.length != 0) {
tbody_height = tbody.height();
tbody.html('<div class="block-loader" style="width:100%"></div>');
}
});
$('#submit_with_answer').click(function() {
if ($.trim($('#text-claim').val()).length > 0)
{
$('#complaint_feedback').submit();
}
else
{
$('#textarea-group').addClass('has-error');
$('#answer_error').html('Заполните поле «Добавить текст ответа»');
}
});
};
</script>
The "_show" view is:
<?php $form = ActiveForm::begin([
'id' => 'complaints',
'action' => Url::to(['complaints/show']),
'method' => 'GET',
'options' =>
[
'class' => 'form-respons form-claimadm',
'data-pjax' => 1,
],
]);
active fields....
<div class="form-btns col-md-2 col-sm-6 col-xs-12">
<?= Html::submitButton('Применить', ['class' => 'btn btn-primary','style'=>"float:right;"]) ?>
</div>
</div>
<?php ActiveForm::end(); ?>
and _handle_form is:
<?php
use yii\widgets\ActiveForm;
use yii\helpers\Url;
?>
<?php
$form = ActiveForm::begin([
'id' => 'complaint_feedback',
'action' => Url::to(['complaints/handle-complaint']),
'method' => 'POST',
'options' => ['class' => 'form-respons form-claim-feedback','style'=>'display:none;'],
]);
?>
<div id="textarea-group" class="form-group">
<label for="text-claim" class="hidden-xs">Добавить текст ответа</label>
<textarea class="form-control" id="text-claim" rows="3" name="complaint_answer" placeholder="Добавить текст ответа"></textarea>
<div id="answer_error" class="help-block"></div>
<input id="complaint_id" name="complaint_id" type="hidden" value="">
</div>
<div class="clearfix form-btns">
<button type="button" onclick="$('#complaint_feedback').submit();" class="btn btn-link">Обработать без ответа</button>
<button id="submit_with_answer" type="button" class="btn btn-primary">Отправить</button>
</div>
<?php ActiveForm::end(); ?>
<a id="hide_handle_form" style="display: none;" onclick="$('#complaint_feedback').hide(); $('.handle_button').removeClass('disabled'); $(this).hide();$('tr[data-key='+$('#complaint_id').val()+']').removeClass('row-open');" class="btn btn-link btn-show-hide">Свернуть
</a>
if I comment lines with pjax, everything works correctly. How can I fix this trouble?
