[Fixed]-Show objects properly as choices in django forms choicefield

Well, as @Anentropic mentioned, I was not on the right way.
And he is right, because I need to submit only answer A or B. But for user on the form I need to display text for these answers from Test model. So I wrote two templatetags for this.
class TestForm(forms.ModelForm):

    class Meta:
        model = TestAnswer
        fields = '__all__'

def communicative_test(request):
    questions = TestModel.objects.all()
    QuestionFormSet = formset_factory(form=TestForm, max_num=questions.count())
    formset = QuestionFormSet(initial=[{'candidate': request.user, 'question': x.number} for x in questions])
    return render(request, 'testing/communicative.html', locals())

Two custom templatetags for each answer (A/B):

@register.filter(name='get_answer1')
def get_answer1(question):
    try:
        question = TestModel.objects.get(number=question)
        answer = question.answer_1
    except ObjectDoesNotExist:
        answer = ''
    return answer


@register.filter(name='get_answer2')
def get_answer2(question):
    try:
        question = TestModel.objects.get(number=question)
        answer = question.answer_2
    except ObjectDoesNotExist:
        answer = ''
    return answer

And template is:

{% load test_tags %}
<form id="communicative-test-form" method="post">
     {% csrf_token %}
     {{ question_formset.management_form }}
     {% for form in question_formset.forms %}
        {% crispy form %}
        {{ form.id }}
        <p>{{ form.question.value }}</p>
        <p><label>
           <input type=radio name="form-{{ form.question.value|add:"-1" }}-answer" id='id_form-{{ form.question.value|add:"-1" }}-answer' value="1">
                        {{ form.question.value|get_answer1 }}
           </label></p>
           <p><label>
              <input type=radio name="form-{{ form.question.value|add:"-1" }}-answer" id='id_form-{{ form.question.value|add:"-1" }}-answer' value="2">
                        {{ form.question.value|get_answer2 }}
              </label></p>
      {% endfor %}
      <div style="text-align: right;" class="col-md-12">
          <button type="submit">Save</button>
      </div>
</form>
