-ActionClosurable extends `UIControl`, `UIButton`, `UIGestureRecognizer`, `UIBarButtonItem` and `NSTimer`.
+ActionClosurable extends `UIControl`, `UIButton`, `UIGestureRecognizer` and `UIBarButtonItem`.
 It helps writing swifty code with closure, instead of target and action like below:
 
 ```swift
 // UIControl
-button.on(.TouchDown) {
+button.on(.touchDown) {
     $0.backgroundColor = UIColor.redColor()
 }
-button.on(.TouchUpOutside) {

 }
