[Moo] NuTabs - Rewrite bindWithEvent for 1.3

[Dailce]

I'm trying to convert Nutabs plugin to mootools 1.3
Seems easy enough, but I can't seem to wrap my head around the rewrite
for the BindwidthEvent

Here is the original plugin:  http://mootools.net/forge/p/nutabs

Here's is my attempt to rewrite it:  http://jsfiddle.net/VELCe/429/

The line that need to fixed is:  tab.addEvent('click',
this.resize.bindWithEvent(this, index));

Thanks.
