Create <input Type="radio"> In IE6?

When I add radio buttons dynamically in IE6 they appear disabled.

Bascially the "checked" status is never visible.

I can set the checked status using the non-standard defaultChecked attribute, or after the element has been appended. But the radios still don't work - the "check" never changes when you click on a different radio input. Also the labels don't work (the radio is only selected if I click on the radio input itself).

The onclick functions I have applied to each radio input work fine.

I've tried several ways of creating the radios - jQuery, vanilla Javascript, etc. but can't get them to work.
