wagtail get_api_representation() not called

Question

I am using Streamfields in Wagtail and got the following problem:

I would like to print out the image path instead of the id and followed the instructions here: Custom representation of Streamfield in rest API

But it seems that get_api_representation() is never called in my case.

urls.py

router.register(r'page', PageView, basename='page')

views.py

class PageView(viewsets.mixins.RetrieveModelMixin, GenericViewSet):
   queryset = Page
   serializer_class = PageSerializer

serializers.py

class PageSerializer(serializers.ModelSerializer):
    class Meta:
        model = Page
        fields = ('title', 'body')

models.py

class APIImageChooserBlock(ImageChooserBlock):
    def get_api_representation(self, value, context=None):
        if value:
            return {
                'id': value.id,
                'title': value.title,
                'image': value.get_rendition('width-1000').attrs_dict
            }


class ImageTextBlock(blocks.StructBlock):
    image = APIImageChooserBlock()
    text = blocks.CharBlock()


class Page(wagtail_models.Page):
    body = StreamField(
        [
            ('MyBlock', ImageTextBlock()),
            ('Newsletter', blocks.StructBlock([
                ('text', blocks.RichTextBlock()),
            ])),
        ]
    )

    content_panels = wagtail_models.Page.content_panels + [
        StreamFieldPanel('body', classname="full",  heading=_('Content'))
    ]

Can somebody identify the problem here?
