Detach Event in spesific ID of tab view

Hello, how i can detach event onAfterTabClick for specified ID of tab view after i clicked view?
My Case , each tabview view will call some request on server side. But in next click tab with same ID view, i want it is not call request again.

Thank You.

try to use onBeforeTabClick event instead and check current tab id

            if(id != this.getValue()){
              // doWork();
