I think that the easy and the safe way, is to get the template of the current view. And get your name, based in the identity, using Ember.TEMPLATES .

Since the TEMPLATES structure is { templateName: compiledTemplate } .

Ember.Handlebars.registerHelper('filename', function(options) {  
  var template = options.data.view.get('template');
  for (var templateName in Ember.TEMPLATES) {
    if (Ember.TEMPLATES[templateName] === template) {
      return templateName;
    }
  }
});
