I am not sure it is a good idea using a Meteor method in a template helper.

A simple solution would be to use an intermediate ReactiveVar. When your template is created, make your method call, and update the ReactiveVar in the callback. Then in your folder helper, simply return the ReactiveVar content.

Meteor will update reactively when your method asynchronously returns.
