Trying to figure out why three $http.gets are fired at a time with this controller.

AngularJsTimer.ts

mod.controller("MyController",
[
    "$scope", "$http",
    ($scope: any, $http: ng.IHttpService) => {
        var queueChecker = setInterval(() => {
            var url = "/foo/count";
            $http.get(url, { params: { cacheBuster: new Date().getMilliseconds() } })
                .success((data: any) => {
                    $scope.QueueView = data;
                    $scope.QueueView.lastUpdated = new Date();
                });
        }, 2500);
        $scope.$on("$destroy", () => { clearInterval(queueChecker); });
    }
]);
