angularjs - get geolocation ionic framework -

i'm working on application in many parts need user's current location. works me today have little problem. in home of application need information use same function use in application

    function success(pos) {       $scope.latitud = pos.coords.latitude       $scope.longitud =  pos.coords.longitude;     }      function error(err) {       alert("el servicio de gps en tu dispositivo esta desactivado.");     };     navigator.geolocation.getcurrentposition(success,error) 

what need know data each time enter in view not it, try in many other parts of project use:

$scope.$on('$ionicview.enter', function(){  }) 

but not work, plus need when loading view or enter fully, action, occupies these geolocation data , connects server run.

      $http({method: 'get', url: url_base+'viewscercanos/'+sessionservice.get("user_id")+'/'+sessionservice.get("hash")+"/"+$scope.latitud+"/"+$scope.longitud})       .success(function(data){         if(data.count > 0){           //solo tres           $scope.views = data.view;           $scope.mostrar_mensaje = false;         }else{           $scope.mostrar_mensaje = true;           $scope.mensaje = "no tienes views en tus registros."         }       })       .error(function(){        })       .finally(function(){         $scope.hide();       }); 

but @ time when action executed latitude , longitude values undefined after print run values , if seteados accordingly. order use in various parts of application , works fine, in particular case, guess may view main must more manage load these values before or during load .
