Having problem adding controllers in application

[owais.zahid]

I am new to sencha touch and trying to create an application using the provided documentation and reading material. I have created a following simple application class:

Ext.application({
    name: 'TestApp',
    constrollers: ['DemoController'],
	
    launch: function () {
        console.log('Application Launch Method is called');
        // some code. 
    }
});

Ext.define('DemoController, {
	extend: 'Ext.app.Controller',	
		
	launch: function() {
		console.log('launch method is called');
	}
});

This code seems to work (as i can't see any errors in the error console). However, I am not seeing any log messages of controller or application launch method.

Can anyone please tell me what I am doing wrong here?

In your Ext.application, you specified constrollers but should be controllers without the first 's'. Does that fix it?
