title: UITextFieldTextDidEndEditingNotification not working properly in TableVIew
body: <p>I have a tableView in which I use an instance of a custom TableViewCell.
  In each custom cell, there's a textfield and a label.</p>
  
  <p>Each time the text on the textField changes, I need to do some update in another textField present on the main UIView of my screen.</p>
  
  <p>There are 6 rows in all</p>
  
  <p><strong>ISSUE</strong>:
  The UITextFieldTextDidEndEditingNotification is triggered only on the 1st, 4th and 6th row on a first attempt.
  Then on a 2nd attempt it would work only on the 1st and 4th.
  When I DEBUG, it WORKS sometimes, but then it again does NOT work.</p>
  
  <p>=> It's like it is working randomly.</p>
  
  <p>I cannot figure out what's going on, anyone can help or provide some hint to track down the cause?</p>
