       1. `constructor()` - The view-model's constructor is called first.
       2. `created(owningView: View, myView: View)` - If the view-model implements the `created` callback it is invoked next. At this point in time, the view has also been created and both the view-model and the view are connected to their controller. The created callback will recieve the instance of the "owningView". This is the view that the component is declared inside of. If the component itself has a view, this will be passed second.
-      3. `bind(bindingContext: Object, overrideContext: Object)` - Databinding is then activated on the view and view-model. If the view-model has a `bind` callback, it will be invoked at this time. The "binding context" to which the component is being boudn will be passed first. An "override context" will be passed second. The override context contains information used to travers the parent hierarchy and can also be used to add any contextual properties that the component wants to add.

       4. `attached()` - Next, the component is attached to the DOM (in document). If the view-model has an `attached` callback, it will be invoked at this time.
       5. `detached()` - At some point in the future, the component may be removed from the DOM. If/When this happens, and if the view-model has a `detached` callback, this is when it will be invoked.
       6. `unbind()` - After a component is detached, it's usually unbound. If your view-model has the `unbind` callback, it will be invoked during this process.
