How to hide attachments based on user role

[chrish5]

I have a need to hide attachments on Stories from users with the scrum_reader role.   I have created the following onLoad client script on the rm_story table, but when I impersonate a user with the scrum_reader role, I am still seeing the attachment.   What am I missing?

function onLoad() {

if(g_user.hasRole('scrum_reader')) {

g_form.disableAttachments();

}

}

I replaced g_form.disableAttachments(); with gel('header_attachment').style.display='none'; and this worked.   Thanks!
