Thanks for catching the problem. Could you please write a test for this.

New test:

1. Write a test module for dc_ajax_add_cart_popup, say dc_ajax_add_cart_popup_test
2. dc_ajax_add_cart_popup_test should update the dc_ajax_add_cart_popup view mode. For example, add a field to the view mode.
3. In the test AjaxAddCartPopupTest, check whether the field is present in the popup.

Attach two patches, one with the fix and the other without the fix. The patch without the fix should fail.
