for writing action fro "go" and "done" button you have to implement the correspondence delegate of your component, for example if you are using a UItextField you have to implement the following delegate -

-(BOOL) textFieldShouldReturn:(UITextField *)textField

Hook the UITextField's Did End On Exit action.
