Unity 5 C# Button.OnClick.AddListener

My code for adding events to my button onclicks dynamically in game does not work. I have gotten other parts of my button to be modified in game, how the onlick code simply will not work and I have tested many solutions. Here is my code (Sorry I don't know how to format) and a few screenshots:

 //The method that IS called (I tested), that mostly works,alt text
 //Except for the onclick part.
 
 public virtual void activateNode()
     {
 
         ConversationController.convCon.button1.onClick.AddListener(delegate { ConversationController.convCon.advanceToNextNode(choice1path); });
 
         //ConversationController.convCon.button1.onClick.AddListener(() => { ConversationController.convCon.advanceToNextNode(choice1path); });
         //COMMENT FOR FORUMS: As you can see, I have already tried to use the "=>" solution, as well as the delegate solution but neither have worked
         //The choicepath values are also successfully loaded, I checked.
 
         ConversationController.convCon.button2.onClick.AddListener(delegate { ConversationController.convCon.advanceToNextNode(choice2path); });
 
         ConversationController.convCon.button3.onClick.AddListener(delegate { ConversationController.convCon.advanceToNextNode(choice3path); });
 
         ConversationController.convCon.button4.onClick.AddListener(delegate { ConversationController.convCon.advanceToNextNode(choice4path); });
 
         //The text loads perfectly, the buttons text are succsessfully modified so I don't get why the addlistener isnt working for the button
         ConversationController.convCon.button1.GetComponentInChildren<Text>().text = choice1;
         ConversationController.convCon.button2.GetComponentInChildren<Text>().text = choice2;
         ConversationController.convCon.button3.GetComponentInChildren<Text>().text = choice3;
         ConversationController.convCon.button4.GetComponentInChildren<Text>().text = choice4;
 
         //This works as well
         ConversationController.convCon.speakerText.text = speakerDialogue;
     }

Again, I want there to be onclick events, but the onclick events do not appear after I attempt to load them.
