I tried this and it seems to work fine for me. More than likely you have a scope issue.

Sure it does. Here is the jsFiddle test -

With your Html revision it works too -

Are you sure the lang variable is within function scope?

Maybe you are missing the document.ready ?

$(function(){
var lang='de';
    $('#en').click(function (){
        lang='en';
    });
});
