WebSocket callback function multiple invocations

Question

I'm trying to create small web application which uses WebSocket protocol to exchange the data

Here is my angular service

define(function () {

    return function (module) {
        return module.service("socketService", function($q, $timeout) {

            var service = {},
                listener = $q.defer(),
                socket = {
                    client: null,
                    stomp: null
                };

            service.RECONNECT_TIMEOUT = 30000;
            service.SOCKET_URL = "/service/booking";
            service.CHAT_TOPIC = "/service/booking/updates";
            service.CHAT_BROKER = "/service/booking";

            service.receive = function() {
                return listener.promise;
            };

            ...
            return service;
       });
   };
});

and also controller code

define(function () {
    return function (module) {
            socketService.receive().then(null, null, function(message) { 
                $scope.list.countDownTimer = 0;
                if(message.resourceId === parseInt($routeParams.resourceId)) {
                    $scope.list.bookings = [];
                }   
                ...     
            });

My problem is that promise.then() callback function is invoked many times and the amount of this invocations is not repeatable: it might be 2 times, 27 or even 110.

One more thing that I should add is that I think that is somehow dependent with amount of users who tests and clicks on the application

Could anyone help? Thank you in advance...
