[TIMOB-27072] When using Alloy Data Binding, allow the dataCollection to be set in the controller

In our application we have a composite view that shares models/collections across many sub views. We also like to utilize data binding wherever possible, however this presents a bit of a challenge. We can only bind to Collections and Models defined in the XML markup, and we cannot replace those Collections/Models with shared references across each sub controller. It appears today our only option is to use a singleton Collection/Model which is not ideal if you need multiple instances of Collections/Models to be accessed across multiple view bindings. If setting the Collection/Model inside the sub controller is not an option perhaps we could introduce a method of passing a reference to the Collection/Model in the createController statement.
