Manually compiling Ember Handlebars templates

I have a scenario where I need to dynamically compile Handlebars templates using ember-cli.

Ember.Handlebars.compile(someString);

I have included the full version of handlebars in Brocfile:

var app = new EmberApp({
    vendorFiles: {
        'handlebars.js': {
            production: 'bower_components/handlebars/handlebars.js'
        }
    }
});

but am getting the following error:

TypeError: undefined is not a function

What am i doing wrong?
