Certain scripts that are attached does not work after build, scene change and closing unity

I am completely new to Unity. I made a UI for a game and attached a few scripts to the canvas. Some of the scripts works as expected while others work right after attaching to the canvas but not after build/scene change/closing Unity.

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 
 public class gotoRoom : MonoBehaviour {
     public Button yourButton;
     GameObject pan;
     void Start () {
         pan = GameObject.Find ("roomPanel");
         Button btn = yourButton.<Button>();
         btn.onClick.AddListener(TaskOnClick);
     }
 
     void TaskOnClick(){
         GameObject.Find("topPanel").SetActive(false);
         pan.SetActive(true);
 
     }
 }

The above code works when i click on the 'room' button.

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 
 public class gotoWindow : MonoBehaviour {
     public Button yourButton;
     GameObject pan;
     void Start () {
         pan = GameObject.Find ("windowPanel");
         Button btn = yourButton.GetComponent<Button>();
         btn.onClick.AddListener(TaskOnClick);
     }
 
     void TaskOnClick(){
         GameObject.Find("topPanel").SetActive(false);
         pan.SetActive(true);
 
     }
 }

The following code does not show the 'window panel' on clicking the 'window' button. What am i doing wrong here? Please help!

yourButton is already a Button, why use GetComponent() ? You could simply do : void Start () { pan = GameObject.Find ("windowPanel"); yourButton.onClick.AddListener(TaskOnClick); } I believe TaskOnClick() must be public to be added as a Listener.
