[jQuery] problem with dynamically setting attributes in IE7

[RandyJohnson]

I have a jQuery routine that adds attributes to elements dynamically.

I am able to retrieve the attribute value via $('#id').attr('attr'))
in FF and Safari.

When I attempt to retrieve the value in IE7 I get a blank value.

If I place the attribute in the original HTML and attempt to read with
IE7 I get the expected attribute value.

Is this an IE7 feature or I am doing something wrong?

Thanks in advance...

Randy
