    store: 'MyStore',
    displayField: 'title',

Listen to the load event of the store for the combobox, and insert an empty record in the handler:

Ext.getStore('MyStore').on('load', function(store) {
    store.insert(0, Ext.create('MyModel', {
        mymodel_id: -1,                  // some invalid id
        title: 'Choose from the list...' // default text for the empty record
    });
});
