How to create a 4.6 UI button NOT from prefab NOT in unity editor only from C#

I've read a lot of questions and answers and watched endless youtube videos but I can't find the answer to this anywhere.

Frequently people suggest instatiating a prefab button or worse ignore the question conditions and just say "drag and drop the button and function".

I really would like to create an entire 4.6 UI button ONLY using C#. complete with mouse over and on click functions.

I have found that the following doesn't work:

   MyButton.onClick.AddListener(() => { MyFunction();})

I create the following example c# code that shows I cannot reach the handleButton method and it does not print "pressed" when I click the invisible button.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using UnityEngine.EventSystems;
 
 public class CreateCanvasButton : MonoBehaviour {
 
 
 
 
     void Start () {
         // create event system
         GameObject eventsystem = new GameObject ();
         eventsystem.AddComponent<EventSystem> ();
         eventsystem.AddComponent<StandaloneInputModule> ();
         eventsystem.AddComponent<TouchInputModule> ();
 
 
         string name = "Canvas";
 
         GameObject newCanvasGO = new GameObject ();
         newCanvasGO.name = name;
         newCanvasGO.transform.SetParent (this.transform);
         newCanvasGO.AddComponent <Canvas>();
         newCanvasGO.AddComponent<CanvasScaler> ();
         newCanvasGO.AddComponent<GraphicRaycaster> ();
 
         RectTransform theCanvasRectTransform = newCanvasGO.GetComponent<RectTransform> ();
         theCanvasRectTransform.anchoredPosition3D = new Vector3 (0f, 0f, 0f);
         theCanvasRectTransform.sizeDelta = new Vector2 (2400f,3800f);

         theCanvasRectTransform.localPosition = new Vector3 (0f, 2.9f, 0f);
         Canvas theCanvas = newCanvasGO.GetComponent<Canvas> ();
         theCanvas.worldCamera = Camera.main;
         newCanvasGO.SetActive (true);
         newCanvasGO.AddComponent<Image> ();
         Image canvasImage = newCanvasGO.GetComponent<Image> ();

         canvasImage.sprite = mySprite;

         // create name title text

Please help I've been trying this for days and have only found unanswered questions such as this one:
