unity - Unity2D: Don't Destroy On Load UI button

I have a UI button as a child under my background canvas. What I want to do is to save the button through out scene, I tried using DontDestroy OnLoad but It saved ay canvas and everything under my canvas, rather than saving just the button. Anyway this is my DontDestroyOnLoad script:

void Awake()
{
    DontDestroyOnLoad(transform.root.gameObject);
}

Thank you. :)

Well I wiped up a script that does this but the solution seem janky. Use it at your own risk.

using UnityEngine;
using UnityEngine.SceneManagement;

public class TestButtonPersist : MonoBehaviour 
{   
    void Awake()
    {
        //We subscribe to  the event for  loading a scene
        SceneManager.sceneLoaded += MyOnLoad;
    }


    void MyOnLoad(Scene scene,LoadSceneMode sceneMode)
    {
        //if our button does not have a parent then we will find it a Canvas.
        if (gameObject.transform.parent == null)
        {
            gameObject.transform.SetParent(
                    GameObject.Find("Canvas").gameObject.transform, false);
            // You might want to use Find with tag here to make sure you will find a canvas
        }

    }

    // This is where the magic happens
    public void LoadLevel()
    {
        // Before we call the code for loading the level, 
        //we make sure to set the button as a root object
        gameObject.transform.SetParent(null,false);
        DontDestroyOnLoad(gameObject);
        SceneManager.LoadScene(1);

    }
}

The thing is you need to call transform.SetParent(null,false) for the object before the scene changes so you will have to do this from your code that loads a new scene.
