How to use CreateView with crispy-forms in Django

I want to use CreateView along with crispy-forms generated layout. However, it seems that everything I pass to self.helper in forms.py is ignored. Form renders nicely, but only with fields generated by CreateView - all fields passed to Layout are missing.

My views.py

class MyView(CreateView):
    form_class = MyForm
    model = MyModel

    def form_valid(self, form):
        pass

My forms.py:

from django.forms import ModelForm, Textarea
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit, Layout
from crispy_forms.bootstrap import FormActions

from .models import MyModel

class MyForm(ModelForm): 

    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper(self)
        self.helper.form_method = 'POST'
        self.helper.add_input(Submit('submit', 'Submit'))
        self.helper.layout = Layout( 
            FormActions(Submit('BlahBlah', 'BlahBlah', css_class='btn-primary')))

    class Meta:
        model = MyModel
        fields = ['xxx', 'yyy']

My image_form.html:

{% load crispy_forms_tags %}
...
<form action="" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form|crispy }}
</form>

What else should I do to make it work?

Solution

Got answer at: https://groups.google.com/forum/#!topic/django-users/Ovp_FgL3YwY

Had to change

{{ form|crispy }}

{% crispy form %}
