Store does not exist unless Ext.create is used

[WagsMax]

I have a store defined as follows:

Ext.define('ATMgo.store.Cases', {
    extend: 'Ext.data.Store',
	storeId: 'casesStore',
    alias: 'store.cases',
    requires: [
        'ATMgo.model.Cases'
    ],


	autoLoad: true,
	model: 'ATMgo.model.Cases',
	proxy: {
		type: 'memory'
	}
});

In Sencha Touch, stores are automatically created, so that after:

var store = Ext.getStore('casesStore');

store has a reference to the store. In Ext, I seem to have to put:

Ext.create('ATMgo.store.Cases', {});

to make the store exist, otherwise after the getStore above, store remains undefined.
Am I missing something that automatically creates the store?

You should be able to call

var store = this.getCasesStore();
