Yii2- Multiple Bootstrap Modal Items on Same Page - yii2

Question

I am creating a page which would hold some buttons for creating different model items loaded via modal.
I'm using this code in a view file: create-all that belongs to the controller: ProductsController
Modal::begin([
'toggleButton' => [
'label' => '<i class="glyphicon glyphicon-plus"></i> Add Product',
'class' => 'btn btn-success'
],
'closeButton' => [
'label' => 'Close',
'class' => 'btn btn-danger btn-sm pull-right',
],
'size' => 'modal-lg',
]);
$class_products = 'app\models\Products';
$productModel = new $class_products();
echo $this->render('/products/create', ['model' => $productModel]);
Modal::end();
Modal::begin([
'toggleButton' => [
'label' => '<i class="glyphicon glyphicon-plus"></i> Add branch',
'class' => 'btn btn-success'
],
'closeButton' => [
'label' => 'Close',
'class' => 'btn btn-danger btn-sm pull-right',
],
'size' => 'modal-lg',
]);
$class_branch = 'app\models\Branch';
$branchModel = new $class_branch();
echo $this->render('/branch/create', ['model' => $branchModel]);
Modal::end();
branch/create code:
<?php
use yii\helpers\Html;
/* #var $this yii\web\View */
/* #var $model app\models\Branch */
$this->title = Yii::t('app', 'Create {modelClass}', [
'modelClass' => 'Branch',
]);
$this->params['breadcrumbs'][] = ['label' => Yii::t('app', 'Branches'), 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="branch-create">
<?php
//echo Yii::$app->request->getReferrer();
$route = parse_url(Yii::$app->request->getReferrer(), PHP_URL_QUERY);
if ($route == urldecode('r=products%2Fcreate-all'))
print_r ($route);
?>
<h1><?= Html::encode($this->title) ?></h1>
<?= $this->render('_form', [
'model' => $model,
]) ?>
</div>
The buttons work just fine and a modal loads for both of the buttons
Problem
Add Product modal adds a new product successfully, but Add Branch doesn't. It just refreshes the page.

An attempt to solve your issue:
As far as I know, simply rendering view file inside the view, will not post data to the controller, unless you specify the action inside the form which you are rendering.
So inside the _form.php
<?php $form = ActiveForm::begin([
'action'=>'your_path_to_the_url',
]); ?>
You can also make an ajax submission from the form and handle the ajax data using Yii::$app->request->isAjax
This is just an idea. I have not seen your controller code nor your forms. Still a wild guess of the problem. See this will help you or not.
