    I just changed grid.js in example directory.
    The listener does not seem to work.

    Code:
    Ext.require([
        'Ext.grid.*',
        'Ext.data.*',
        'Ext.util.*',
        'Ext.state.*'
    ]);
    
    Ext.onReady(function() {    
        Ext.QuickTips.init();
     
        // sample static data for the store
        var myData = [

                                alert('click : ' + record.get('company'));
                            }

    Not even this works ...
    It looks like a bug.

    Code:
        grid.addListener('dblclick', function() {
               alert("aaa")
            }
        );
