Hello Everyone ,
                       I am working on Custom Calendar in VisualForce page. I follow  steps from this  http://www.codebycody.com/2013/06/create-calendar-view-in-salesforcecom.html . Everything is doing fine but i dont know how to add new event in custom calendar on click on date.
So any idea how i can add new events ??
My controller

public class CalendarExample_Controller {



    public Boolean includeMyEvents {get;set;}

    public list<calEvent> events {get;set;}

    

    //The calendar plugin is expecting dates is a certain format. We can use this string to get it formated correctly

    String dtFormat = 'yyyy-MM-dd HH:mm:ss';

    

    //constructor

    public CalendarExample_Controller() {

        //Default showing my events to on

        includeMyEvents = true;

    }

    

    public PageReference pageLoad() {

        events = new list<calEvent>();

        //Get Contact's Birthdays

        for(Contact cont : [select Id, Birthdate, FirstName, LastName from Contact where Birthdate != null]){

            //here we need to replace the birth year with the current year so that it will show up on this years calendar

            DateTime startDT = datetime.newInstance(Date.Today().Year(),cont.Birthdate.Month(), cont.Birthdate.Day());

            calEvent bday = new calEvent();

            

            bday.title = cont.FirstName + ' ' + cont.LastName + '\'s Birthday!';

            bday.allDay = true;

            bday.startString = startDT.format(dtFormat);

            //Because this is an all day event that only spans one day, we can leave the send date null

            bday.endString = '';

            bday.url = '/' + cont.Id;

            bday.className = 'event-birthday';

            events.add(bday);

        }

        

        //Get Campaigns

        for(Campaign camp : [select Id, Name, StartDate, EndDate from Campaign where IsActive = true]){

            DateTime startDT = camp.StartDate;

            DateTime endDT = camp.EndDate;

            calEvent campEvent = new calEvent();

            

            campEvent.title = camp.Name;

            campEvent.allDay = true;

            campEvent.startString = startDT.format(dtFormat);

            campEvent.endString = endDT.format(dtFormat);

            campEvent.url = '/' + camp.Id;

            campEvent.className = 'event-campaign';

            events.add(campEvent);

        }

        

        //Get my Events if we have selected the correct option

        if(includeMyEvents){

            for(Event evnt: [select Id, Subject, isAllDayEvent, StartDateTime, EndDateTime from Event where OwnerID = :UserInfo.getUserId()]){

                DateTime startDT = evnt.StartDateTime;

                DateTime endDT = evnt.EndDateTime;

                calEvent myEvent = new calEvent();

                

                myEvent.title = evnt.Subject;

                myEvent.allDay = evnt.isAllDayEvent;

                myEvent.startString = startDT.format(dtFormat);

                myEvent.endString = endDT.format(dtFormat);

                myEvent.url = '/' + evnt.Id;

                myEvent.className = 'event-personal';

                events.add(myEvent);

            }

        }

        return null;

    }

    

    public PageReference toggleMyEvents() {

        if(includeMyEvents){

            includeMyEvents = false;

        }

        else{

            includeMyEvents = true;

        }

        pageload();
