> This change is to add a new ValueUpdatedEvent + ValueUpdatedListener where ValueUpdatedEvent will be queued within UIXEditableValueTemplate.updateModel method.
> This is to allow components and etcetera to listen to this event by adding a listener in the new UIXEditableValueTemplate.addValueUpdatedListener API.
> The pro of adding this event + listener is that various components can then listen when the value has been updated in the model.
> This is beneficial in
> 1) Clearing up any data that would have been persisted for some reason [i.e. if the app wished to keep a temporary value of a component using some kind of polling from client to server to not lose any dirty data {i.e. how confluence wiki allows users to preserves the old states}].
> 2) To avoid sending a certain asynchronous dirty data from the client to the server
> Thanks!
