Show-Hide columns not working

[GoogleCodeExporter]

Show - Hide button is not working in the showcase (and in my app). The error in 
file jquery.struts2.min.js says "Uncaught TypeError: Cannot call method 
'replace' of undefined"

What steps will reproduce the problem?

1. Go to http://struts.jgeppert.com/struts2-jquery-showcase/index.action
2. Press button Show/Hide Columns
3. Nothing happends
This happends also in my code but showcase is a really easy way of showing it

What is the expected output? What do you see instead?

This should raise a dialog to sleect visible columns. Instead nothing happends 
(really an error happends)

Which struts2 version?
2.3.15

Which struts2-jquery plugin version?
3.5.1

Please provide any additional information below.

Looks like onClickTopics for buttons are not working. As a current workaround 
you can use Anchor tag. See Showcase commit above.

Now the dialog rises but hiding or showing columns does not work at all. I will 
file a new bug to explain this.
