There is one important rule when using uiloos: you may never directly manipulate any of the fields of the components! Otherwise the subscribers will not be informed, and changes to the "live" properties will not be detected.

So always use the appropriate methods to realize the changes you want to see, so the components can keep the observers / subscribers in the loop.

Another rule is that you should not be using anything inside of the components that start with an underscore. These classes / methods / instance fields should be considered private. We reserve the right to change their names / inner workings and not consider it a breaking change! So please do not use and depend on them.
