How to make the calendar event text editable on click?

I'm trying to implement this calendar plugin

http://jsfiddle.net/minusplus/7a7gG/2/

What I can't figure out is how to make the calendar event text editable when it is clicked.

Looking through the documentation for the plugin, I can't find a method to call to edit the event text. The only example that shows how to开发者_JAVA技巧 set the text is upon initialization using a title indicator (to set it below to "Lunch with Mike"):

var eventData = {
    events : [
       {"id":1, 
       "start": new Date(year, month, day, 12), 
       "end": new Date(year, month, day, 13, 35),
       "title":"Lunch with Mike"},
    ]
};

Using the event eventClick you need to edit the data to store whatever value for the eventData.events.title you want, and then render it again, $(”#calendar”).weekCalendar(”today”);

I have never used this plugin, but this is what it looks like you need to do based on how I read the documentation.
