Hello, I am trying to reference one of my stores in my controller and it seems it's not loading at the time of the call. I am using

Code:
console.log(Ext.getStore('MyStore').count());
but the result is 0

If I tie it to a button handler an click it I get 10, so this is telling me it is not loaded yet in the controller. I looked at the docs and it seem there is a launch function that executes after the application, however this code does not run, any thought on how to access my store?

Code:
 Ext.define('tapp.controller.MyController', {
        extend: 'Ext.app.Controller',
        views: ['MyApp'],
        stores: ['MyStore'],
        launch: function (){
            console.log('LLLLAAAUNCHEDDDD');
        },
