Your second alert is executed before the CheckStoreAvailability is called due to asynchronous call. That is why you are not getting the updated value.

Check the answer in this post how function call is used with done(), you may change your call accodingly.

AJAX is asynchronous, so that alert(isOk); line is going to be executed before the AJAX call has completed, and by extension before the value has been changed by the AJAX requests callback function.

If you want to work with that value, do it inside that function handling a response from the AJAX call.
