Form Plugin - using multiple times on the same form

Form Plugin - using multiple times on the same form

I'm using the Form Plugin to allow a user to upload a photo.
The user clicks on a link in the page and I display a dialog collecting the file and description.
It works great the first time, but when they do it again the description and a hidden field is not passed in the form.

How can I get the form to work more than once without reloading the page?

I call this on the click of the link on the page.

var options = {target: '#divToUpdate', success: PhotoUploaded};
$('#photoForm').ajaxForm(options);

Thanks
