Getting Data Bank from Gantt Chart

[Henry Tran]

I am using the Gantt Chart provided by Google. 

I have added a listener to when I click on any of the elements or entity in attempt to return the row/columns data, but it is returning empty, 

Anyone have any code where it can return the rows data?

Here is my attempt on jsfiddle: https://jsfiddle.net/30cuaarb/

And this is what I am trying to do: I click on Spring 2014. In the console, it returns a empty object, I want that object to return the data within the row of Spring of 2014.

Thanks for reading!
