Django cms creation wizard form

Question

I have an Article model with CharFields,models.DateTimeField and FilerFileField. I create form like this:

class ArticleWizardForm(forms.ModelForm):
    class Meta:
        model = Article
        exclude = []

    class Media:
        js = 'admin/js/jquery.init.js', #this not working

and creation wizard like this:

class ArticleWizard(Wizard):
    pass

article_wizard = ArticleWizard(
    title="Article",
    weight=200,
    form=ArticleWizardForm,
    description="Create a new Article",
)

wizard_pool.register(article_wizard)

It works fine with trivial CharFields but models.DateTimeField and FilerFileField don't have same widgets like in django admin. You can see differences in the following screenshot (Django admin on right)! I figured out that django JS is not loaded so I add it to Media. However it wasn't added to the template. So I hard code it to cms\wizards\base.html and jquery.init.js was successfully loaded but widgets always look like on the image.

Question is, how can I reach same look and functionality in creation wizard like in django admin?

And why media is not loaded in template?

original cms\wizards\base.html

{% block extrahead %}
    {{ block.super }}
    <script type="text/javascript" src="{% static_with_version "cms/js/modules/jquery.noconflict.pre.js" %}"></script>

    <script type="text/javascript" src="{% static_with_version "cms/js/modules/jquery.noconflict.post.js" %}"></script>
    {{ form.media }}
{% endblock %}
