Just what Evan Trimboli said, with the checkchange event on the grid you can capture when a checkbox changes value.

Ext.create('Ext.grid.Panel', {
    //...
    columns  : [{ 
        xtype: 'checkcolumn',
        header: 'Enabled',
        dataIndex: 'isEnabled',
        width: 55,
        listeners: {
            checkchange: function(column, rowIdx, checked, eOpts){
                //Logic here
            }
        }
    }],
});

There is a little change in the give answer, the checkchange event is for Ext.grid.column.check not for Ext.grid.Panel

Ext.create('Ext.grid.Panel', {
//...
columns  : [{ 
    xtype: 'checkcolumn',
    header: 'Enabled',
    dataIndex: 'isEnabled',
    width: 55,
    listeners: {
        checkchange: function(column, rowIdx, checked, eOpts){
            //Logic here
    }
    }
}]
});
