        if ($model->save()) {             
            return $this->redirect(['view', 'id' => $model->id]);             
        }
    }

    return $this->render('create', [
        'model' => $model,
    ]);
}

to

<?php
public function actionCreate()
{
    $model = new Company();

    if ($model->load(Yii::$app->request->post())) {
        if ($model->save()) {             
            if (Yii::$app->request->isAjax) {
                // JSON response is expected in case of successful save
                Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
                return ['success' => true];
            }
            return $this->redirect(['view', 'id' => $model->id]);             
        }
    }

    if (Yii::$app->request->isAjax) {
        return $this->renderAjax('create', [
            'model' => $model,
        ]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

View

<?php
use karnbrockgmbh\modal\Modal;

Modal::begin([
    'id' => 'createCompany',
    'url' => Url::to(['/partner/default/create']), // Ajax view with form to load
    'ajaxSubmit' => true, // Submit the contained form as ajax, true by default
    // ... any other yii2 bootstrap modal option you need
]);
Modal::end();
