Answer 1

In Javascript this is referes to diffrent objects depending on how a function is called. In your example you are receiving function from view model and then execute it.

 var v = viewModel.get('v')();

In that case this inside function is referes to 'Window' object. To avoid this error you should call function as viewModel member.

 var v = viewModel.v();

or manually set this to viewModel via bind/apply/call methods.

 var v = viewModel.get('v').call(viewModel);
