How to call controller function in view in extjs

I have one function in controller. It will return a value. I have called that function in view using renderer:this.getController('test.controller.Barchart').change(); but it is not working. I am getting an error wind has no method getController(). Can anybody tell me how to call it correctly?

Having a view call a controller is considered the essence of evil. The view should never be aware of the controller. I'm a lead on a large project that uses ExtJS and we don't allow anything in our views other than the JSON description of the view. The logic that is looking for a controller should likely be in the controller itself.

Try this: You can put your controller as a global variable in your app.js like so:

Ext.define('MySharedData', {
    my_Controller:Object

});

In your controller: 

MySharedData.my_Controller=this.getController('<ControllerfolderPath>.controllerName');

then call the function that you want, from your view:

 MySharedData.my_Controller.my_Function();

please refer below solution!!!

var ControllerRef=<applicationreference>.getController(<ControllerfolderPath>.controllerName);
ControllerRef.<ControllerFunction>();

Example:

var MyApp = Ext.create('Ext.app.Application', { 
               ......
               ......
            });

var ControllerRef  =   MyApp.getController('general.ManagerController');
ControllerRef.MyFunction();

Thanks
