JSON load to DataView doesn't work

[MrBeef]

Any mistakes in the following code? I've been trying again and again but my JSON load doesn't work...I just see "Loading..." for several seconds then just a blank screen. I've tried loading via AJAX too, but that doesn't show the "Loading..." screen. Thanks in advance for the assistance.

Sample of my JSON data:

{"households":[{"HHName":"Jim Smith Household"}])

Ext.regModel('Household', {
    fields: [
        {name: 'HHName',    type: 'string'}
    ]
});

var store = Ext.create('Ext.data.Store', {
        model    : 'Household',
        proxy: {
            type: 'jsonp',
            url: 'get_households.php',
            reader: {
                type    : 'json',
                root: 'households'
            }
        },
        autoLoad: true
    });

var list = Ext.create('Ext.DataView', {
        store: store,
        itemTpl: '<p>household name is {HHName} </p>'
    });
