For Android

To set remainder you have have to create event like :

// Create the event
var eventBegins = new Date(2010, 11, 26, 12, 0, 0);
var eventEnds = new Date(2010, 11, 26, 14, 0, 0);
var details = {
    title: 'Do some stuff',
    description: "I'm going to do some stuff at this time.",
    begin: eventBegins,
    end: eventEnds
};

var event = calendar.createEvent(details);

// Now add a reminder via alert for 10 minutes before the event.
var reminderDetails = {
    minutes: 10,
    method: Ti.Android.Calendar.METHOD_ALERT
};
event.createReminder(reminderDetails); 

(Note: Not fully tested code just for an idea) try it..
