Template Call Helpers Explicitely.

It looks like it is possible as of Meteor 1.0.3.1 to find and call helper functions, although it is clear it's not supposed to be used like this.

Still it can be done:

Template.foo.__helpers[" fooFn"]()

Please notice the leading space for the function name.

The other way of dealing with this is attaching a function to a global namespace, then calling that from somewhere else in your code, as user3557327 mentioned.

Additionally you can use:

Template.registerHelper('myHelper', function (){return 'Look At Me!'})

to register a global helper, and call it explicitly using:

UI._globalHelpers['myHelper']()
