I'm making progress with the basics of uibuilder, but not quite following how to catch changes in "dynamic" data. Let's say I want to catch a value change in the client side **jQuery** app using the uibuilder pattern:

```auto
  uibuilder.onChange( 'myState', function(newVal) {
      console.info( 'myState changed!' )
      console.log( 'myState:' , newVal )
      ... some cool code ...
  })

```

Is it possible to set the value in a _node-red_ function using something like `uibuilder.set('myState','unconfused')` so the the onChange callback above spots changes? Or is that not how dynamic values work? Can I only use the getter and setters within the jQuery side code? So in that case, I would use a Node Red function to set the `{key:value}` inside the `msg.payload` and then use `uibuilder.onChange('msg',callbackFn)` just to get the _payload_ (which means I have to store the previous `key:values` in jQuery code to look for changes)?

You will have to feed data into the uibuilder node. It remains a node-red-node, meaning, passing messages.
