title: Programmatically create UITextField events
body: <p>I some add textfields programmatically into a TableView when the rows are created. I am trying to subscribe to the TouchUpInside event of these textFields by doing this</p>
  
  <pre><code>UITextField *eTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 12, 145, 25)];
  eTextField.delegate = self;
  [eTextField addTarget:self action:@selector(showPicker)
  forControlEvents:UIControlEventTouchUpInside];
  </code></pre>
  
  <p>showPicker is an IBAction with no parameters.It never  gets fired. Is there something I else I need to do?</p>
  
  <p>Is there something I'm missing? 
  Thanks in advance</p>
