So I have a Ext.ux.form.SuperBoxSelect component that uses an Ext.data.SimpleStore like this

```
var myData = [];

var myStore = new Ext.data.SimpleStore({
        id: 0,
        fields: ['id', 'name'],
        data: myData,
        ......
    });

var boxSelect = new Ext.ux.form.SuperBoxSelect({
        fieldLabel: 'xxx',
        width: xxx,
        mode: 'local',
        hiddenName: 'xxx',
        valueField: 'xxx',
        displayField: 'xxx',
        value: xxx,
        store: myStore
    });

```

Now the value of myData variable will be updated as the user makes AJAX calls. How do I reload the SuperBoxSelect so its list items will also be updated realtime?
