推送器存在无法使用angularjs和golang获取成员

I am trying to use the examples from here so far this is what I have setup

// angularjs

    // JS
    var presenceClient = new Pusher('API_KEY', {
        authEndpoint: apiServer + "/presence_auth",
        authTransport: 'jsonp',
        encrypted: true            
    })


    var c = pusher.subscribe("presence-testchan")
    Utils.log(c.members.count) // 0
    Utils.log("000============")    
    c.bind('pusher:subscription_succeeded', function(members) {
        Utils.log("succeeded?")
        Utils.log(members)
    })

// golang and the presence endpoint

func Presence(w http.ResponseWriter, r *http.Request, next http.HandlerFunc) {
    params, _ := GetBytes(r.URL.String())

    presenceData := pusher.MemberData{
        UserId: database.GenerateStrObjID(),
        UserInfo: map[string]string{
            "twitter": "pusher",
        },
    }
    response, err := PusherClient.AuthenticatePresenceChannel(params, presenceData)

    if err != nil {
        panic(err)
    }

    respondToJSON(w, string(response))
}


func respondToJSON(w http.ResponseWriter, data interface{}) {

    r := render.New()
    r.JSON(w, http.StatusOK, data)
}

I guess that is the basic form. but I don't get any members count?. I can get a response from the API with

"{\"auth\":\"7d6e393c49c579c43a0c:6cd45662ef57fbc3ab16d8052c43bf95e7415846f736c2499bac7628ca3b75bc\",\"channel_data\":\"{\\\"user_id\\\":\\\"56f9e5ffcc1cb466a624a3cf\\\",\\\"user_info\\\":{\\\"twitter\\\":\\\"pusher\\\"}}\"}"

but has error

Uncaught SyntaxError: Unexpected token :

Am I missing something or my setup is wrong?

    NVM, solved the problem.. it's missing in the docs for Go examples to return it in jsonp with callback func. response should have something like this...

    Pusher.auth_callbacks['1']({auth: "7d6e393c49c579c43a0c:33a442fcc9d3bf67febfeeb59e5a8e4f0364901069534cdef006b0b047df9f75",…});
    auth:"7d6e393c49c579c43a0c:33a442fcc9d3bf67febfeeb59e5a8e4f0364901069534cdef006b0b047df9f75"
    channel_data :"{"user_id":"56fa1231cc1cb48a1cdb243c","user_info":{"twitter":"pusher"}}"
