You can achieve this with a renderer:

for example: 

Ext.create('Ext.grid.Panel', {
    title: 'Column Demo',
    store: myStore,
    columns: [{
        text: 'b_id',
        renderer: function (value, meta, record) {
            return record.getb().get('id');
        }
    }],
    width: 400,
    forceFit: true,
    renderTo: Ext.getBody()
});
