#Relevent parts to explain action, routes in Ember 1.0pre
##Action Helper
The {{action}}
helper registers an HTML element within a template for
DOM event handling and forwards that interaction to the Application's router,
the template's Ember.View
instance, or supplied target
option (see 'Specifiying a Target').
User interaction with that element will invoke the supplied action name on
the appropriate target.
(Example without Router skipped, check helpers/action.js)
