Updating a Kino frame with Kino.Markdown within a grid

Edit: This was a user error. This scenario works fine.

I am trying to build a Kino grid that looks like this:

Cell 1:

md = Kino.Markdown.new(mermaid_graph)
md_frame = Kino.Frame.new()

...create buttons...

Kino.Shorts.grid([md_frame, button_frame])



Then, I want to periodically update that markdown within a process, like this: 

```elixir
  def render(meta) do
    new_diagram = diagram()
    Kino.Frame.render(meta.frame, new_diagram)

    %{meta| diagram: diagram}
  end

If I do this, the original frame within the grid never updates.

Cell 2

But, I can then create a new cell using the same frame, and I can see it update periodically. How do I update a frame within a grid? I can already animate my Kino.VegaLite plots and Kino.DataTable tables, but not my Mermaid diagrams. Any advice?

Are you trying to render the new diagram directly into the frame? By the looks of it, you might need to do a new markdown Kino from the new diagram then render that markdown kino.

If you post more of the code it’ll be easier to diagnose

Thanks for looking!

I figured it out a few minutes ago. It was a coding error.
