Django nested inlines not working?

I've installed django-nested-inline but I have problems. Here's my code:

from django.contrib import admin
from nested_inline.admin import NestedStackedInline, NestedModelAdmin
from .models import Positive, Negative, Option, Question

class PositiveInline(NestedStackedInline):
    model = Positive

class NegativeInline(NestedStackedInline):
    model = Negative

class OptionInline(NestedStackedInline):
    model = Option
    inlines = [PositiveInline, NegativeInline,]

class QuestionAdmin(NestedModelAdmin):
    fieldsets = [
        (None,               {'fields': ['question_title']}),
        ('Date information', {'fields': ['pub_date'], 'classes': ['collapse']}),
    ]
    inlines = [OptionInline,]

admin.site.register(Question, QuestionAdmin)

When I try to add a new Question, I have this error:

AttributeError at /admin/question/question/add/

'OptionInline' object has no attribute 'queryset'

Am I doing something wrong?
