how can I override Backbone.parse to parse this?

account.coffee

define ["backbone", "models/account"], (Backbone, Account) ->
  	class Account extends Backbone.Model

	Account

accounts.coffee

define ["backbone", "models/account"], (Backbone, Account) ->
	class Accounts extends Backbone.Collection
		model: Account
		
		parse: (response) ->
			response.results

	Accounts

logged collection.json

[Object]
0: Object
{ "results": [ { "username": "b1service1", "jacket": "0�000", "auth_id": "000", "email": "email@domain.com", "business_channel": "N/A" }, { "username": "b1service2", "jacket": "0001", "auth_id": "0001", "email": "email1@domain.com", "business_channel": "N/A" } } ], "error": null } : Object
collection: Accounts
previousModels: Array[0]
silent: true
__proto__: Object
__proto__: Object
length: 1

response.json

{
  "results": [
		{
			"username": "b1service1",
			"jacket": "000000",
			"auth_id": "000",
			"email": "email@domain.com",

    {

	],
	"error": null
}
