What is visible for templates (and how) depends on the ObjectWrapper,
which is (normally) part of the freemarker.template.Configuration
object. In most configurations what you try to do should work, because
the default ObjectWrapper (and BeansWrapper) does expose methods by
default. However, even these object wrappers can be configured to hide
methods, for example with
theObjectWrapper.setExposureLevel(BeansWrapper.EXPOSE_SAFE).

Another rare but rather mean cause of methods becoming invisible is
that the object whose method you want to call implements
java.util.Map. In that case you can only get the Map keys, not the
methods and JavaBean properties.
