How to refresh a component from another component ?

[CedricRaison]

I have a ListPostView component which list my posts.

class ListPostView(UnicornView):
    posts = []

    def mount(self):
        self.posts = list(Post.objects.all().order_by('-created_at'))

I have another component which is a form to create a new post.

I would like after saving a new post to refresh my ListPostView to display my new post.

class CreatePostView(UnicornView):
    content = ""

    def save(self):
        if self.content:
            post = Post.objects.create(content=self.content)
            self.content = ""
            # refresh ListPostView so it can show my new post.
