After loading page with ajax, submit button in active form not working/responding

hi, how to debug a create button in a form? I have clicked the button but not responding.

first, when not filling the fields, and click the create button, it will validate the fields.
after filling the fields, and click the create button, it is not responding.

please help. thanks.

What is your debug toolbar displaying?

this is the debug toolbar. after click the create button, nothing happen.

I clarify my question. I have active form, i called a popup modal to show information (contain gridview) and select the row tobe loaded to the active form page. after loaded the information to active form page, the submit button won’t work/not responding.
Please advise me. thanks before.

this is the button i called the modal.

<?php $form = ActiveForm::begin(); ?>
            
            <?= $form->field($model, 'ref_id')->textInput(['maxlength' => true, 'readonly' => false]) ?>
            <div id="BtnSearchPengiriman">
                <?= Html::button('Search Pengiriman Produksi', [
                    'value' => Yii::$app->urlManager->createUrl('/pengiriman-produksi/list'),
                    'class' => 'btn btn-primary',
                    'id' => 'BtnModalPengiriman',
                    'data-toggle' => "modal",
                    'data-target' => "#modalPengiriman",
                ]) ?>
            </div>

this is the section which i loaded the information.

 <?php ActiveForm::end(); ?>
        </div>
        <div class="col-xs-6">
            <div id="view-pengiriman"></div>
        </div>
    </div>
    <?php
    Modal::begin([
        'header' => 'List Pengiriman Produksi',
        'id' => 'modalPengiriman',
        'size' => 'modal-lg',
        'class' => 'style=width:auto'
    ]);
    echo "<div id='modalContent'></div>";
    Modal::end();
    ?>

ajax function

$('#BtnModalPengiriman').click(function(e){    
    e.preventDefault();
    $('#modalPengiriman').modal('show')
        .find('#modalContent')
        .load($(this).attr('value'));  
    return false;
})

code that is loaded into modal and return view to active form

$(document).on('click', '.select-row', function(){
    // get id from custom button    
    var id = $(this).attr('data-id');

    $.get('../pengiriman-produksi/get-data', {id : id}, function(data){
        $('#penerimaanproduksi-ref_id').val(id);
        $('#view-pengiriman').html(data);
        $('#penerimaanproduksi-bruto').focus();
     });
     $('#modalPengiriman').modal('hide');
});

entire code
