there's a mix of $scopes there

there is this event fired

$rootScope.$broadcast("CallParentMethod", {});

therefore you should be listening for this event in a child $scope, but you're listening to it in $rootScope

$rootScope.$on("CallParentMethod", function() {
    $scope.getUserDetails();
})

you might want to listen for it in the same scope in which getUserDetails() is defined

$scope.$on("CallParentMethod", function() {
    $scope.getUserDetails();
})

Another hint: if you don't need to pass any parameters, you can ignore the empty object {} when $broadcasting

$rootScope.$broadcast("CallParentMethod")
