How can I convert my JSON response's key from snakecase to camel case?

I just started using Rails for my web application's framework. Now I'm working on an API for a test project. I want the key of my API's JSON response to be camelcase instead of snakecase. How can I do that?

My JSON respond is something like this: 

{"id":3,"name":"Bingo Gem", ..., "can_purchase":true,"shine":6,"created_at":"2014-07-31T06:34:37.917Z","updated_at":"2014-07-31T06:34:37.917Z","reviews":[]}

The response I expected:

{"id":3,"name":"Bingo Gem", ..., "canPurchase":true,"shine":6,"createdAt":"2014-07-31T06:34:37.917Z","updatedAt":"2014-07-31T06:34:37.917Z","reviews":[]}

Here's one of my controllers:

module Api
    module V1
        class PermataController < ApplicationController
            respond_to :json

            def index
                respond_with Permatum.all, :include => [:reviews]
            end

        end
    end
end

and routes.rb:

namespace :api, defaults: { format: 'json'} do
    namespace :v1 do
      resources :schedules
      resources :permata
    end    
  end

In Rails, there is a method camelize in String class. Use it:

"can_purchase".camelize(:lower) #=> "canPurchase"
"created_at".camelize(:lower)   #=> "createdAt"
