Question

I am a beginner in Angularjs and working on some else project.
how can I get data of $scope.selAppt from bookingToolCtrl into reasonDialogCtrl?
(function () {
app = angular.module('bookingToolApp', ['ngSanitize', 'ui.bootstrap', 'isteven-multi-select', 'angucomplete-alt', 'ngTable', 'dialogs.main', 'ngMap', 'BookingToolServices', 'BookingToolDirectives']);
app.run(['$templateCache', function ($templateCache) {
$templateCache.put('/dialogs/reason.html', '<div class="modal-header"> <h4 class="modal-title"><span class="glyphicon glyphicon-calendar"></span> Reserve Service {{selAppt.selected.eventid}}</h4></div><div class="modal-body"><ng-form name="nameDialog" novalidate role="form"><div class="form-group input-group-lg" ng-class="{true: \'has-error\'}[nameDialog.username.$dirty && nameDialog.username.$invalid]"> <label class="control-label" for="course">Reason:</label> <input type="text" class="form-control" name="reason" id="reason" ng-model="reason" ng-keyup="hitEnter($event)" required> <span class="help-block">Enter the reason for reserving this service.</span></div></ng-form></div><div class="modal-footer"><button type="button" class="btn btn-default" ng-click="cancel()">Cancel</button><button type="button" class="btn btn-primary" ng-click="save()" ng-disabled="(nameDialog.$dirty && nameDialog.$invalid) || nameDialog.$pristine">Submit</button></div>');
}]);
app.controller('bookingToolCtrl', ['$scope', 'dataService', '$sce', 'NgTableParams', '$filter', '$compile', '$rootScope', 'loadingEventService', 'claimantLatLngEventService', 'dialogs', '$timeout', 'ngTableEventsChannel', function ($scope, dataService, $sce, NgTableParams, $filter, $compile, $rootScope, loadingEventService, claimantLatLngEventService, dialogs, $timeout, ngTableEventsChannel) {
$scope.selAppt = {"selected": false};
}]);
app.controller('reasonDialogCtrl', function ($scope, $modalInstance, data) {
});
})();
I tried the following but it doesn’t work:
app.controller('reasonDialogCtrl', ['$scope', '$modalInstance', 'data', 'dataService', '$controller','$rootScope', function ($scope, $modalInstance, data, dataService, $controller,$rootScope) {
//-- Variables --//
$scope.data = dataService.data;
$scope.service = dataService;
var testCtrl1ViewModel = $controller('bookingToolCtrl');
alert(testCtrl1ViewModel.selAppt);
}]);
$scope.selAppt get values when I select an appointment.

In bookingToolCtrl
$scope.selAppt = {"selected": false};
dataService.data = $scope.selAppt //... you missed this
and in reasonDialogCtrl
$scope.data = dataService.data;
