Ext.create on prototype is bad!

bad.js

Ext.define('MyApp.view.Grid', {
    extend : 'Ext.grid.Panel',
    xtype  : 'myapp-grid',
    
    //...
    
    plugins : [
        //Bad!
        Ext.create('Ext.grid.plugin.CellEditing', {
            clicksToEdit : 1
        })
    ]
});

good.js

Ext.define('MyApp.view.Grid', {
    extend : 'Ext.grid.Panel',
    xtype  : 'myapp-grid',
    
    //...
    
    plugins : [
        //Good!
        {
            ptype        : 'cellediting',
            clicksToEdit : 1
        }
    ]
});
