Javascript SetInterval执行脚本，每个间隔13次

Question

So here is my script, I don't understand at all what is happening.

var reloadTableInterval = setInterval(function(){
    console.log('ABC');
}, 120000);

When I do this, I notice that it writes 13 time the "ABC" in my console everytime the interval is completed. I'm wondering if I'm doing something wrong?

Note that this function is part of a AngularJS(1.3) controller.

app.controller('unitCtrl', ['$scope', '$http', '$compile', function($scope, $http, $compile){
    //...
}]);

Also, I have 7 directive that uses my Controller, they are all built this way but with different name:

app.directive('clientInfoModal', function () {
    return {
        restrict: 'E',
        replace: true,
        templateUrl: '/reservations/template/ClientInfoModal.html',
        controller: 'unitCtrl'
    };
});

And they are loaded at the bottom of my HTML document (it's a single page small application)

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js"></script>
<script src="js/app.js"></script>
<script src="js/controller/unitController.js"></script>

Edit: Fixed answer based on OP's question comment thread

app.service('intervalCheckService', ['$interval', function($interval) {
  return {
    intervalRun: false,
    setInterval: function() {
      if (!intervalRun) {
        this.intervalRun = true;
        var reloadTableInterval = $interval(function() {
          console.log('ABC');
        }, 120000);
      }
    }
  }
}]);

Include that service in your app as a dependency. Then inject it into your controller.

app.controller('unitCtrl', ['$scope', '$http', '$compile', 'intervalCheckService', function($scope, $http, $compile, intervalCheckService) {
  intervalCheckService.setInterval();
  //...
}]);

The angular docs has a great example of a service as well if you need more examples: See Here
