I am using that https://github.com/angular-ui/ui-calendar to use the FullCalendar in Angularjs.

It displays the calendar and showing no errors;

Answer 1

I used

$scope.callCalendar = function (){
... ...
};

and in html file:

The events doesn't show up in the calendar; but I found the $scope.events has correct value in console.log($scope.events).
