I have an element that when is clicked receives a new class - foo . I've made a .resizable function on that element but it does not work:

$(".foo").resizable({
            aspectRatio: 1/1,
            autoHide: true

If ad in html a <span id="foo">some text</span> that does not dinamically gets a "foo" class it works fine.
How should I use .resizable for newly created DOM elements?

Thanx.
