Why is InvokeRepeating not working in boolean method?

I'm trying to kill two birds with one stone by putting some logic in a boolean method. By itself the boolean method does what it's supposed to. The CancelInvoke works as well. However, with the InvokeRepeating there, it doesn't work or return true. I have to manually change the distance to make it true. What is wrong?

 float range = 5f; //The Range

 private bool InRange () {
     if (Vector2.Distance(transform.position, targetPosition) <= range) { //Get Distance
         if (!IsInvoking("TheMethod")) { //Incase not invoking
             InvokeRepeating("TheMethod", .5f, .5f); //Doesn't work and doesn't return true
         }

         return true;
     } else {
         CancelInvoke("TheMethod"); //cancels invoke
         return false;
     }
 }
