  Example:
1. Create two inputFields (one for the title and one for the message).
2. Create a button that will be responsible for sending a message.
3. Attach the UIScript to any GameObject on the scene.
4. Fill out all the required fields.
5. Go to the submit button, click plus icon under OnClick() event,
select GameObject with attached UIScript, then select the OnClick() method in UIScript.

(or use eventSystems + public void OnPointerClick(EventSystems.PointerEventData eventData))
