if a.isEdit  is true , then {!NOT(a.isEdit)} is false
if a.isEdit  is false , then {!NOT(a.isEdit)} is true

Hope you get your answer

Hello Dushyant,  
i have confusion about ( ! and NOT) which one convert  true  to false and false to true
(! is Not operator convert true to false)
(NOT also not  convert  true to false)

In Visualforce , ! this use to bind the variable  

If you use !!, then it will work as NOT

if a.isEdit  is true , then  {!!a.isEdit} is false
if a.isEdit  is false , then {!!a.isEdit} is true


single ! is only used to bind varibales or field in visualforce

Hope you get your answer
