Angularjs $interval returns fn is not a function
<p>I want to check if cookie exists with $interval. I am calling $interval on page load. This call periodically throws an error:</p>

<pre><code>&gt; TypeError: fn is not a function
&gt;     at callback (angular.js:12516)
&gt;     at Scope.$eval (angular.js:17444)
&gt;     at Scope.$digest (angular.js:17257)
&gt;     at Scope.$apply (angular.js:17552)
&gt;     at tick (angular.js:12506)
</code></pre>

<p>I really don't understand why.</p>

<p>Here is my code:</p>

<pre><code>angular.module("appModule")
.controller("loginController", ["$scope", "$http", "$window", "$document", "$interval", "$cookies",
    function ($scope, $http, $window, $document, $interval, $cookies) {

    var stopInterval;
    $scope.CheckLoginCookie = function () {

        if ($cookies.get("Login") != null) {

            if (angular.isDefined(stopInterval)) {
                $interval.cancel(stopInterval);
                stopInterval = undefined;
            }

            $window.location.href = $scope.UrlNotes;
        }
    }

    $scope.Repeat = function ()
    {
        stopInterval = $interval($scope.CheckLoginCookie(), 1000);
    }
}]);
</code></pre>

<p>Code is being called from $document.ready:</p>

<pre><code>$document.ready(function () {      
    $scope.Repeat();
})
</code></pre>
