RACBinding between UITextfield and a target that sends a signal when the text is changed programatically or using the keyboard.
- (RACSignal *)bindTextfield:(UITextField *)textField target:(id)target keypath:(NSString *)keypath

RACObservablePropertySubject *textFieldTextProperty = [RACObservablePropertySubject propertyWithTarget:textField keyPath:@keypath(textField,text)];
