dom-node macro does not update on atom change about devcards

[bhauman]

This is an interesting one.
I'm wondering what the behavior should be.

Here is a solution in the meantime:

(def render  (fn [state node]
      (set! (.-innerHTML node) (str "Click me count: " (:count @state)))
      (set! (.-onclick node) #(swap! state update-in [:count] inc))))) 

(defn render-on-change [render-fn] 
   (fn [state node]
        (add-watch state :rendering (fn [_ _ _ _] (render-fn state node)) ;; idempotent
        (render-fn state node)))

(defcard dom-node-updating
  "Seems dom-node doesn't update?"
  (dom-node (render-on-change render)
  {:count 0}
  {:inspect-data true})

The parens may be wrong, this is just a quick sketch.

Thanks much, that should do the trick for now.

I ran into this too and came up with a similar solution, but I also notice that the history controls don't appear when the state first changes. They show up after I save the file and Figwheel reloads or make a second state change.

good point, that makes sense
