So I have code like this that I want to execute every time an accordion item is opened or closed:

1. var tabletContent = parseFloat($('.twoCol').css("height") + $('.sideColumn').css("height"));
2.         if (tabletContent > 400)
3.         {
4.         $('#sidebar').css("min-height",tabletContent);
5.         }
6.         else
7.         {
8.         $('#sidebar').css("min-height",400);
9.         }

I've tried to insert it into $.widget in places that seem relevant, like

1. if(_this.opened){
2.                 _this.close();
3.             }

But tabletContent ends up not being the actual value of for example the expanded content. The value changes somewhat, I can see that in FF dev tools, but it's like 1000px when it should be 1400px etc.
How to go about this?
