Beginner Help: Grid not loading data

[lucasite]

Hi, I hope someone can help, Im very new to ExtJs.
Im simply trying to populate a simple grid with some data from an ajax request.
However the grid loads, but there's no data. And firebug show no request either.
Im abit stumped.

Here's my code:

Ext.BLANK_IMAGE_URL = '/scripts/extjs/resources/images/default/s.gif';

Ext.onReady(function() {
    
    var ds = new Ext.data.JsonStore({
        url: 'Home/Get',
        root: 'data',
        idProperty: 'Id',
        sortInfo: {
            field: 'Name',
            direction: 'ASC'
        },
        fields: [
            {name: 'Id', type: 'int'},
            {name: 'Name', type: 'string'},
            {name: 'Salary', type: 'float'},
            {name: 'Active', type: 'boolean'}
        ]
    });
    
    var colModel = new Ext.grid.ColumnModel([
        { header: "Id", width: 60, sortable: true},
        { header: "Name", width: 150, sortable: true, id: 'company'},
        { header: "Salary", width: 100, sortable: true},
        { header: "Active", width: 100, sortable: true, resizable: false}
     ]);
 
    var grid = new Ext.grid.GridPanel({
        store: ds,
        colModel: colModel,
        width: 600,
        height: 300,
        title: 'My GridPanel',
        frame: true        
    });
    
    
    new Ext.Container({
        renderTo: document.body,
        items: [grid]
    });
});

I cannot figure what Im doing wrong, can anyone spot it?

Embarrassingly I found it almost straight away after posting.
So for anyone else that reads this in future, JsonStore doesnt automatically load the data unless you add the option autoLoad: true

Problem solved.
