There is no Change listener for fieldset.You should listen to change event inside the selectfield

{
                    xtype: 'fieldset', 
                    items: [{
                            id: 'selVehiclename',
                            xtype: 'selectfield', 
                            store:'itemvehicles',
                            valueField:'itemID',       
                            displayField: 'name',
 listeners:{
                         change: function(slider, thumb, obj1, val) 
                         {
                             console.log('some info');
                         }
                    }                                 
                            }],

                },
