This is a template of my page, I want it has a button "show/hide" at right top to collapse/ uncollapse the content, but it's not working

http://vi.deche.wikia.com/wiki/Template:Mienbac_Navbox

And sample at liquidpedia, it workes normally: http://wiki.teamliquid.net/dota2/Teamplate:The_International_Navbox

I don't find the error, my common.js and common.css is likely liquidpedia's one

Can somebody help me?
