How to make a request in an Angular loop?

Question

JavaScript

The controller has a request:

.controller('estateCtrl', function ($scope,reqFac,$state) {
        reqFac.post('c=seller&a=showEstate',$scope.estate, function (res) {
            $scope.estate = res;
            if(res['st']=='error'){
                $state.go('login');
            }
        });
})

How to force it to be called through SetInterval?
It is not possible to simply wrap or call through variable assignment

setInterval(controller....);
