Unable to call geolocationerror when gps is disabled

When gps is enabled geolocationsuccess work perfectly. But when gps diabled it not calling geolocationerror in mobile device.Working on ionic framework using phonegap geolocation for checking is gps enable or not. codes are here

var locOptions = {
      maximumAge : 10000,
      timeout : 5000,
      enableHighAccuracy : true
    };
function onLocationSuccess(position) {
    console.log(position);
    // alert('success');
    $rootScope.pos = new google.maps.LatLng(position.coords.latitude,
                                                     position.coords.longitude);
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({'latLng': $rootScope.pos}, function address(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            if (results[1]) {
                $rootScope.currentposition = results[1].formatted_address;
                console.log($rootScope.currentposition);
                if($scope.switchToState=='signedIn'){
                        $ionicLoading.hide();
                        $http.get($rootScope.url +'api/price/?key=movo1026868hk738hkl')
                            .success(function(response) {
                                $rootScope.truckfare=response.datasets;
                            });
                    console.log('reached here2');
                        $state.go('app.home');
                    }
                    else{
                            $ionicLoading.hide();
                        $state.go('start');
                    }
            }
        }
    });
}

// onError Callback receives a PositionError object
//
function onLocationError(error) {
    alert("Geolocation error: #" + e.code + "\n" + e.message);
}
navigator.geolocation.getCurrentPosition(onLocationSuccess, onLocationError, locOptions);
