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.

Since I learning/working with ExtJS not that long ago I've a question. How do you handle view listener events without calling controller? Say I have a grid, and I want to execute a controller function on row select event? How do you do that without calling controller from view listener?
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

it's not exactly MyApp reference, but reference to View that has this controller set. In my application I call LoginBtn.click of LoginWin with this code:
Ext.ComponentManager.get('LoginWin').getController().onLoginClick(); while MyApp is another window.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();
