This exists in 5.0.18. Note that the method must be public. This
assumes you have a method named getMethod(), that is, a property named

Support for passing parameter values was added in 5.1. Previously you
could only invoke zero-args methods.
Thiago is right, however, that past a certain point, you will want to
create a method in your Java class as this starts to severely break
down the separation of concerns between the view and the controller,
and leaves you increasingly open to refactoring errors.
