Call controllers functions, but how?

[mcbl]

I have an App called APP,
a controller called loginController and
a controller's function called doLogin().

How to call that doLogin() function when needed? For example in a button tap action, in controller.

I tried with something like this, without success:
APP.controller.loginController.doLogin();

How to call ANY function in a controller?

Need your help!

Controllers get events from components.

So, doLogin() method should be triggered by some action like button click.

Add a button to your view then add a controller action to your controller which routes click event of that button to the doLogin().

May be you need to learn a little bit about ExtJS / Touch...
