Assuming your Submit button is the Form's native Submit Button, that will send a POST request back to the Suitelet. The Suitelet can then perform whatever POST functionality it needs to, and then use
context.response.sendRedirect()

Thanks Eric. I tried this one but still not working. Is the type incorrect?
context.response.sendRedirect({           type: http.RedirectType.MEDIA_ITEM,           identifier: folderID                             });
