Input Field Problem

I have been all day trying to change my code and add Input Field instead answers, but with no progress, this is my code:

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 using System.Collections.Generic;
 
 public class QuestionDialogMulti : QuestionDialogBase {
 
     // Prefab za toa kako izgleda eden odgovor
     public GameObject answer;
 
     // Momentalno prasnje so povekje odgovori
     private MultiQuestionXMLBase.Question currentQuestion;
     private MultiQuestionXMLBase questionBase;
     // Transform komponentata na dialogot
     private RectTransform rect;
     // Lista na objekti odgovori
     private List<GameObject> answers;
     // Visina
     private float height;
 
     void Start () {
 
         questionBase = GameObject.FindWithTag("QuestionBase").GetComponent<MultiQuestionXMLBase> ();
         // Zemame transform
         rect = GetComponent<RectTransform> ();
         // Zemame visina
         height = rect.sizeDelta.y;
         // Kreirame prazna lista od odgovori
         answers = new List<GameObject>();
 
     }
 
     // Pri prikaz generiraj novo prasanje
     public override void SetVisible(bool visible) {
         base.SetVisible(visible);
         if (visible) {
             SetQuestion();
         }
     }
 
 
     public void SetQuestion() {
 
         // Gi briseme site predhodni odgovori
         foreach (GameObject go in answers) {
             Destroy(go);
         }
         answers.Clear();
 
         // Generirame novo prasanje
         currentQuestion = questionBase.Questions[Random.Range (0, questionBase.Questions.Count)];
         // Go postavuvame tekstot na prasanjeto
         question.text = currentQuestion.question;
         // Za sekoj odgovor
         for (int i = 0; i < currentQuestion.answers.Count; i++) {
             // Kreirame nov objekt odgovor (od prefabot za izgled na odgovor)
             GameObject tmpAnswer = (GameObject) Instantiate(answer);
             // Go dodavame vo listata na odgovori
             answers.Add(tmpAnswer);
             // Go vgnezduvame  vo dialogot
             tmpAnswer.transform.SetParent(transform, false);
             // Mestime tekst na odgovorot
             Text tmpText = tmpAnswer.GetComponentInChildren<Text>();
             tmpText.text = currentQuestion.answers[i].answer;
             // Mestime koja funkcija da se povika pri klik na odgovorot
             tmpAnswer.GetComponent<Button> ().onClick.AddListener(
                 () => ButtonClicked(tmpText));
             // Mestime pozicija vo dijalogot
             RectTransform tmpRect = tmpAnswer.GetComponent<RectTransform> ();
             //Ne treba ova
             //tmpRect.anchoredPosition = new Vector2(tmpRect.anchoredPosition.x, tmpRect.anchoredPosition.y - (tmpRect.rect.height * i));
         }
         // Go zgolemuvame dijalogot za da gi sobere site odgovori
         rect.sizeDelta = new Vector2(rect.sizeDelta.x, height + (answer.GetComponent<RectTransform>().rect.height * (currentQuestion.answers.Count - 1)));
 
         
     }
 
     // Funkcija koja se povikuva pri klik na odgovor.
     public void ButtonClicked(Text value) {
 
         // Ako e tocen odgovorot povikaj event Answered ako ne generiraj novo prasanje
         string text = value.text;
         for (int i = 0; i < currentQuestion.answers.Count; i++) {
             if (text == currentQuestion.answers[i].answer) {
                 if (currentQuestion.answers[i].correct) {
                     Answered();
                 } else {
                     SetQuestion();
                 }
                 break;
             }
         }
 
     }
 
 }
 

The script is in this object http://i.imgur.com/T1PZEqV.jpg, and i have prefab Answer which has Button script and child with text script. So my code now is generating as clones answers as i have in my QuestionBase. And door opens if the correct answer is clicked.

But i cant figure out how to make different type of answer with Input Field so when the right answer is typed the door to get oppened. Tnx for ur time :D
