How to sort store by multiple fields?

[luciano.lima]

I'm trying to sort a store by two fields, but only the first sort works.
Store is loaded in controller. The data is requested but only first sort is applied.

Ext.define('Events', {
    extend: 'Ext.data.Store',
    config: {
        model: 'Event',
        storeId: 'events',
        sorters: [
            {
                property: 'timestamp',
                direction: 'ASC'
            },
            {
                property: 'title',
                direction: 'ASC'
            }
        ]
    }
});

Ext.define('Event', {
    extend: 'Ext.data.Model',
    config: {
        idProperty: 'id',
        fields: [
            {name: 'id', type: 'int'},
            {name: 'title', type: 'string'},
            {name: 'description', type: 'string'},
            {name: 'image', type: 'string'},
            {name: 'url', type: 'string'},
            {name: 'category'},
            {name: 'tags'},
            {name: 'timestamp'}
        ]
    }
});

Only sort by the first sorter.
I tryed this another code in store on sorters field

        sorters: [
            {
                sorterFn: function (event1, event2) {
                    console.log('sorter 1');
                    var data1 = event1.get('datetime').valueOf().toString(),
                        data2 = event2.get('datetime').valueOf().toString();
                    return data1.localeCompare(data2);
                },
                direction: 'ASC'
            },
            {
                sorterFn: function (event1, event2) {
                    console.log('sorter 2');
                    var title1 = event1.get('title'),
                        title2 = event2.get('title');
                    return title1.localeCompare(title2);
                },
                direction: 'ASC'
            }
        ]

And on the console only print severals 'sorter 1' and no one 'sorter 2'.
How I can sort by multiple fields?

This don't work too

var store = Ext.getStore('events');
store.sort([            {
                sorterFn: function (event1, event2) {
                    console.log('sorter 1');
                    var data1 = event1.get('datetime').valueOf().toString(),
                        data2 = event2.get('datetime').valueOf().toString();
                    return data1.localeCompare(data2);
                },
                direction: 'ASC'
            },
            {
                sorterFn: function (event1, event2) {
                    console.log('sorter 2');
                    var title1 = event1.get('title'),
                        title2 = event2.get('title');
                    return title1.localeCompare(title2);
                },
                direction: 'ASC'
            }
        ]);
