found a typo,

try this

gs.hasRole('itil,sn_change_write') &&( new ChangeFormUI(current).isAuthorizeAvailable() || (current.type == 'standard' && current.state=='-5') && !(current.type =='standard' && current.short_description.toString().indexOf('informational standard change') >-1))

Ok its because of the case, try this

gs.hasRole('itil,sn_change_write') &&( new ChangeFormUI(current).isAuthorizeAvailable() || (current.type == 'standard' && current.state=='-5') && !(current.type =='standard' && current.short_description.toString().toLowerCase().indexOf('informational standard change') >-1))
