bootstrap3 pretty-fullcalendar meteor not reactive in blaze - meteor

Question

I'm using a bootstrap3 pretty-fullcalendar in a project and pre blaze, when I changed some properties of an event (such as color) it was immediately reflected in the display on the calendar. Now, when I change the attribute, I have to reload the calendar manually to have the change show up.
I'm instantiating the calendar in the template render function as
Template.packLayout.rendered = function(){
$('#calendar').fullCalendar({
//dayClick:function( date, allDay, jsEvent, view ) {
// Requests.insert({title:'Request',start:date,end:date,color:'red',className:'todo'});
// Session.set('lastMod',new Date());
//},
eventClick:function(reqEvent,jsEvent,view){
Session.set('editingReqEvent',reqEvent.id);
Session.set('showEditEvent',true);
},
eventDrop:function(reqEvent){
Requests.update(reqEvent.id, {$set: {start:reqEvent.start,end:reqEvent.end}});
Session.set('lastMod',new Date());
},
events: function(start, end, callback) {
var events = [];
reqEvents = Requests.find();
reqEvents.forEach(function(evt){
event = {id:evt._id,title:evt.title,start:evt.start,end:evt.end,color:evt.color};
events.push(event);
})
callback(events);
},
editable:true,
weekMode: 'liquid'
});
}
Has something changed that would make this happen?

Here is how i managed to get it working:
1) keep your calendar code as per "rendered"
Template.calendar.rendered = function () {
console.log('Calendar - running redered');
Session.set('calendarTemplateRendered', true);
var entries = Calendar.find().fetch(),
$calendar = $('#calendar');
$calendar.html('').fullCalendar({
header: {
left: '',
center: '',
right: ''
},
contentHeight: 1100,
defaultDate: '2014-01-12',
defaultView: 'agendaWeek',
editable: true,
selectable: true,
selectHelper: true,
select: function (start, end) {
var title = prompt('Event Title:');
var eventData;
if (title) {
eventData = {
title: title,
start: start,
end: end
};
$('#calendar').fullCalendar('renderEvent', eventData, true); // stick? = true
}
$('#calendar').fullCalendar('unselect');
},
events: entries
});
Add a autorun:
Deps.autorun(function () {
if (Session.equals('calendarTemplateRendered', false) ||
!calendarSubs.ready() ||
typeof Calendar === 'undefined') {
console.log('exiting because there is no objects to process');
return;
}
console.log('trying to autorun');
var entries = Calendar.find().fetch(),
$calendar = $('#calendar');
$calendar.fullCalendar('removeEvents');
$calendar.fullCalendar('addEventSource', entries);
$calendar.fullCalendar('rerenderEvents');
}
Blaze will do the rest for you - (redraw the UI properly). Now you can just modify your Calendar subscription as you like and it will work perfectly.
