8 years ago Hey! yes its legit :-) Your case is something we're working on and expect in the next release within the next couple of weeks. We'd like to support both data binding and the ability to add event listeners.
At the moment you can supply a form action function which will render a button, where you could show your preview, but it sounds like you would like the preview updated as you update fields.
For that case at the moment you can supply your change function directly to the form schema per the aplaca documentation.
I'll go ahead and keep this issue open to track. I might ping you if I need implementation help

I'd like to be able to run an action whenever the content of the form changes.
My use case is a dynamic-form that gets used to render some UI. I'd like to offer live preview for the changes a user makes in the form:
My component structure involves an 'editor' that exposes a computed property for the schema of the dynamic form component. My understanding of Ember's data flow is that the dynamic form component should not mutate the parent's data, rather it should call an action to update that data. It looks like alpaca supports observing form changes: http://www.alpacajs.org/docs/api/observables.html.
Does this seem like a legitimate use case? I'd be happy to implement this feature.
