New UI Text through script?

i have tried accessing the new UI Text through script using other examples from answers and the one in the Unity tutorial but it did not work.

what i have tried:

 using UnityEngine;
 using System.Collections;
 
 public class NewBehaviourScript : MonoBehaviour {
 Text text;
 
     // Use this for initialization
     void Start () {
     text = GetComponent<Text>();
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 }
