found out that you can't remove 2 class at the same time.
With the Edge runtime only, you can add only single class using addClass and remove single class using removeClass.
When you include jquery, then addClass and removeClass can add/remove multiple classes in one go.
You are right. Your point is taken for consideration.
Correction to my earlier comments:
addClass in Edge API can add multiple classes. (No problem)
removeClass in Edge API can only remove one class at a time. (Problem)
We'll fix the removeClass so that it'll behave just as jQuery removeClass function, even if jQuery is not included in new Edge composition.
The patch (EA 2014.1.1) with the fix is live now.
