It sounds like you mean "uninstall" a patch. Adding custom actions in patches doesn't work out so well. Patches essentially apply transform to the existing MSI then repair the MSI. In the case of uninstalling a patch, the transform is removed and the MSI is repaired. Obviously, if the custom action is removed with the transform then it has no chance to run.
The Windows Installer does special magic to keep track of the state of the MSI before and after the transform so they can properly remove data.
