Use the delegate()^[docs] method to bind the handler to the .column container.

Example: http://jsfiddle.net/zgWr3/3/

$('.column').delegate("input.numeric:text",'keyup',function () {
    $val = $(this).val().match(/[0-9]/g).reverse().join("").match(/[0-9]{1,3}/g).join(",").match(/./g).reverse().join("");
    $(this).val($val)
});

This way, any "input.numeric:text" elements inside of .column will invoke the handler irrespective of when they’re added to the DOM.

I also changed the selector around a little. Seems more understandable to me.
