(Unity) My Text UI not updating

Ok, so, i try to make something like a quizz, where an array of strings has to be shown to the Text UI. Thing is, the question updates in the inspector after i answer it correctly, however it doensn't on the game screen. Prob a noob mistake, sorry i'm newbie.

     public string[] quesitons = new string[] { "2+2 = ?", "1+1 = ?", "3+3 = ?" };
     public string[] answers = new string[] { "4", "2", "6" };
     public int i = 0;
 
     [SerializeField]
     private InputField _input;
 
     //Main
     public string currentQ;
     public string currentA;
 
     public Text questionText;
 
 
     public void GetInput(string input)
     {
         if (input == answers[i])
         {
             Debug.Log("Correct");
             i++;
             questionText.text = quesitons[i];
             currentQ = quesitons[i];
             currentA = answers[i];
         }
         else
         {
             Debug.Log("Wrong");
         }
     }
 
     void Start()
     {
         currentQ = quesitons[i];
         questionText.text = quesitons[i];
 
         currentA = answers[i];
     }
 }
