yii2 boostrap 5 and modal - yii2

Question

Edit:
I discovered that if i do a clean install, the modal works, and it's after adding hail812/yii2-adminlte3 that the modal system won't work anymore... but i don't find what create this,
original:
little question, does any of you use yii/boostrap5/modal and succeed to render ajax form in a modal ? Because my code used with the older bootstrap won't work.. and i don't find how the new yii/bootstrap5/modal works...
here is my code
<?php
yii\bootstrap5\Modal::begin([
'id' => 'modal',
'size' => 'modal-lg',
//keeps from closing modal with esc key or by clicking out of the modal.
// user must click cancel or X to close
'clientOptions' => ['backdrop' => 'static', 'keyboard' => TRUE]
]);
echo '<div id="modalContent"></div>';
yii\bootstrap5\Modal::end();
?>
<?php
$this->registerJs( <<< EOT_JS_CODE
$(function(){
// changed id to class
$('.modalButton').click(function (e){
e.preventDefault();
$.get($(this).attr('href'), function(data) {
$('#modal').modal('show').find('#modalContent').html(data)
});
document.getElementById('modalHeader').innerHTML = '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button><h4>' + $(this).attr('title') + '</h4>';
return false;
});
});
EOT_JS_CODE
);
?>
the link i use to open the modal:
<?= Html::a(Yii::t('app', 'Ajouter'), ['create-categorie'], ['class' => 'btn btn-success modalButton','title'=>'Nouvelle catégorie']) ?>
And my code in my controller
public function actionCreateCategorie()
{
$model = new Categorie();
if ($model->load(Yii::$app->request->post())) {
$model->created_at = strtotime('now');
$model->updated_at = strtotime('now');
if( $model->save()){
return 'success';
}else{
return 'error';
}
}
return $this->renderAjax('create-categorie', [
'model' => $model,
],false, true);
}
my console with a strange error i don't get
