[jQuery] Equal Columns After DOM

[jQuery] Equal Columns After DOM


I'm trying to use jquery to keep my columns equal in height. The
problem is that when I expand something in my menu in one of those
columns, the height doesn't re-adjust. I'm thinking it's because it's
only called when document.ready...
I don't know the event very well, but is there a way I could call this
so when the height adjusts?
code:
function equalHeight(group) {
    tallest = 0;
    group.each(function() {
        thisHeight = $(this).height();
        if(thisHeight > tallest) {
            tallest = thisHeight;
        }
    });
    group.height(tallest);
}
$(document).ready(function() {
    equalHeight($(".column"));
});
