Why I can not call method from another one in the same controller?

Question

I try to call method that returns View inside of another method, but in the same controller. There is my code:

public ActionResult GetAnswer(List<PossibleAnswerVM> possibleAnswers)
{
    if (IsLastQuestion(possibleAnswers.FirstOrDefault().IdQuestion))
    {
        return Index();
    }
    return null;
}
[HttpGet]
public ActionResult Index()
{
    IEnumerable<Anketa> anketas = Manager.SelectAnketa();
    return View(anketas);
}

And there is the form which call GetAnswer()

@using (Ajax.BeginForm("GetAnswer", "Survey", FormMethod.Post,
    new AjaxOptions { InsertionMode = InsertionMode.Replace }))
{
    <input type="submit" value="Ответить" 
        onclick="answerClick(@Model.FirstOrDefault().OrdQuestion);" 
        class="btn btn-default" />
}

Also I have tried RedirectToAction() and call methods from another controller.
I would appreciate any help.

When you say you cannot call that method what exactly do you mean? Are you getting a compilation error, a runtime exception? If so please post the message you are getting. — juharr, May 25 '16 at 13:48
Actually the problem is that nothing happens. Process goes to breakpoint at the `return Index();` statement, and then goes inside the `Index()` method but appropriate `View` does not appear. — Vitalii Isaenko, May 25 '16 at 13:53
@David alredy posted. Edited the post by addind code of the method. — Vitalii Isaenko, May 25 '16 at 14:03
@VitalyIsaenko Ive editted my answer just don't call the index, return the view straight from the GetAnswer() — David, May 25 '16 at 14:05
@VitalyIsaenko see below answer edited again return View("VIEWNAME", anketas); — David, May 25 '16 at 14:07
@AlessandroD'Andria I supposed that it can affect. And tried to change to `@Html.BeginForm()`. Unfortunately it didn't help either. — Vitalii Isaenko, May 25 '16 at 14:08
@AlessandroD'Andria I'm really sorry, you were right. I changed another view. Can you please to help me understand why doesn't it work with ajax call? And how to do it using ajax? — Vitalii Isaenko, May 25 '16 at 14:16
Take a look at this [SO question](http://stackoverflow.com/questions/7430976/rendering-partial-views-using-ajax). — Alessandro D'Andria, May 25 '16 at 14:22
@AlessandroD'Andria Thank you, I tried offered code, but it didn't help me. I suppose that in accepted answer code does the same thing as `Ajax.BeginForm()` does. Am I right? Nevertheless, I couldn't solve the problem this way. — Vitalii Isaenko, May 26 '16 at 06:49

Try this.

public ActionResult GetAnswer(List<PossibleAnswerVM> possibleAnswers)
{
    if (IsLastQuestion(possibleAnswers.FirstOrDefault().IdQuestion))
    {
          IEnumerable<Anketa> anketas = Manager.SelectAnketa();
          return View("VIEWNAME", anketas);
    }
    return null;
}

private static bool IsLastQuestion(int idQuestion)
{
    var returnValue = false;

    Question question = Manager.GetQuestion(idQuestion);
    List<Question> questions = Manager.SelectQuestions(question.idAnketa);

    if (questions.Count == Manager.GetCountQuestionsAnswered(question.idAnketa, SessionUser.PersonID))
    {
        returnValue = true;
    }                      
    return returnValue;
}

I tried to return `View()` instead of `Action()`, but it didn't help too. In addition, I need to initialise object for strongly-typed view. – Vitalii Isaenko May 25 '16 at 14:01
@VitalyIsaenko can you post the code in your Index() method, ive changed above to return the index() - nice to see whats in there. – David May 25 '16 at 14:02
yes, this approach helped, thank you. But why can't I return method instead of view? – Vitalii Isaenko May 25 '16 at 14:18
