grid column sort option greyed out

[remiszej]

I don't understand why the sort option for my grid columns is disabled (greyed out) although I use sortable : true configuration. Any help would be greatly appreciated.

My grid with store and model are attached.

Perhaps I missed something?

Ext.create('Ext.data.Store', {
    storeId : 'simpsonsStore',
    fields  : [
        {
            name : 'name', sortType : Ext.data.SortTypes.asUCString
        }, 
        'email', 
        'change'
    ],
    data    : {'items' : [
        { 'name' : 'Lisa',  'email' : 'lisa@simpsons.com',  'change' : 100  },
        { 'name' : 'Bart',  'email' : 'bart@simpsons.com',  'change' : -20  },
        { 'name' : 'Homer', 'email' : 'home@simpsons.com',  'change' : 23   },
        { 'name' : 'Marge', 'email' : 'marge@simpsons.com', 'change' : -11  }
    ]},
    sorters : { property:'name', direction:'ASC' }, // default sort
    proxy   : {
        type   : 'memory',
        reader : {
            type : 'json',
            root : 'items'
        }
    }
});

Ext.create('Ext.grid.Panel', {
    title      : 'Simpsons',
    store      : Ext.data.StoreManager.lookup('simpsonsStore'),
    columns    : [
        { header : 'Name', dataIndex : 'name', sortable: true },
        { header : 'Email', dataIndex : 'email', flex : 1, sortable: true },
        { header : 'Change', dataIndex : 'change', sortable: false } // disable for grins
    ],
    height     : 200,
    width      : 400,
    renderTo   : Ext.getBody()
});

Scott, thank you for your reply.

Your code is pretty much what I have, and the code that I attached always worked for me. The only twist now is
that in the controller I add filter to this grid's store. However, on startup filter is not applied and sort options in the column header are still grayed out (disabled).

After some troubleshooting I found out that my problem was buffered configuration for the store.
Once I removed that, column sorting is back.

Thanks for the update.

Scott.
