You have some options:

• Override toJSON to return the computed duration

• Create a duration() method on the Backbone Model. Only downside that you have to call it differently (obj.duration() instead of obj.get('duration')). In your view that hands obj.toJSON() to your template, mix in the duration attribute

• Use https://github.com/asciidisco/Backbone.Mutators (or similar) to create a derived getter for duration
