php – How to regenerate a modal with an active form

I’m running in to this issue that when I create a modal with an active form, and I close the modal without submitting the form, it doesn’t get reset when I try to recreate it.

Basically I want to load a different model by changing the parameters the button sends to the controller, while using the same action. However it looks like the action only executes the first time.

I use the following code for the button

<div class="btn-group">
                <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                    Create <span class="caret"></span>
                </button>
                <ul class="dropdown-menu">
                    <li><?php echo Html::a('From Library', ('/library/physical/create', 'params' => ('type_id' => PhysicalTypes::ControlModule)));?></li>
                    <li class="divider"></li>
                    <li><?php echo Html::a('Area', ('create-modal','params' => ('type_id' => PhysicalTypes::Area,)), ('data-toggle'=>'modal', 'data-target'=>'#modalphysicalcomponentcreate'));?></li>
                    <li><?php echo Html::a('Process Cell', ('create-modal','params' => ('type_id' => PhysicalTypes::ProcessCell,)), ('data-toggle'=>'modal', 'data-target'=>'#modalphysicalcomponentcreate'));?></li>
                    <li><?php echo Html::a('Unit', ('create-modal','params' => ('type_id' => PhysicalTypes::Unit,)), ('data-toggle'=>'modal', 'data-target'=>'#modalphysicalcomponentcreate'));?></li>
                    <li><?php echo Html::a('Equipment', ('create-modal','params' => ('type_id' => PhysicalTypes::Equipment,)), ('data-toggle'=>'modal', 'data-target'=>'#modalphysicalcomponentcreate'));?></li>
                    <li><?php echo Html::a('Control Module', ('create-modal','params' => ('type_id' => PhysicalTypes::ControlModule,)), ('data-toggle'=>'modal', 'data-target'=>'#modalphysicalcomponentcreate'));?></li>
                </ul>
            </div>

Then in my controller I use the following

public function actionCreateModal(array $params)
{
    ...

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(('view', 'id' => $model->id));
    }

    return $this->renderAjax('_modal_form', (
        'actionTitle' => 'Create new',
        'model' => $model,
    ));

}

And at last my modal code that gets rendered.

<?php
  use yiihelpersHtml;
  use yiiwidgetsActiveForm;
  use yiihelpersArrayHelper;
  use yiihelpersStringHelper;

?>
<?php 
$form = ActiveForm::begin(
    ('enableClientValidation' => true, 'options' => ('id' => 'modal-form')));
?>

<div class="modal-header">
    <button type="button" class="close" data-dismiss="modal">&times;</button>
    <h4 class="modal-title"><?= $actionTitle ?> <?= StringHelper::basename(get_class($model)); ?></h4>
</div>
<div class="modal-body">
    ...
</div>
<div class="modal-footer">
    <?php echo Html::submitButton('Save', ('class' => 'btn btn-success')) ?>
    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>

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

So I want to be able to close the window, click a different button, and load a new model into the modal.
All help is appreciated!
