CSV, Excel, Print button show up but nothing happens when I click them

hemalait

I need to use CSV, Excel and Print buttons. Print seems to be working fine but when I click CSV or Excel nothing is happening. I have defined buttons in same fashion for a previous application, I am reusing that exact pattern but over here its not working. Here is the DataTable declaration, please help me find what am I doing wrong?

I tried using DataTable debug which shows that I am using older version of tabletools. I have another application where it works with the same older version, I am using the same version.

I removed the whole code and added line by line and tested along with this process, I don't know what but the issue is fixed now (magic!). I checked the line and word count they are same. Also I did a before and after compare that yielded no differences.
