jQuery Flip front to 2 different backsides

I am having trouble getting a certain feature to work.

As you can see here: http://ift.tt/1F5JkhP

<div> CHECK CODE AT JSFIDDLE</div>

I am using the flip jquery plugin which made a flip, where you choose a category, and then gets sent to a certain login screen. My issue is, that I want the bottom one to flip to another backside. I have tried altering the jquery plugin, but without luck. Is there anyone who knows how I could make this work?

So the pink one goes to the pink login, and the blue one goes to the blue login.

Thank you in advance!
