Extjs 4.1 - Looking for a event inside a combo That listen the Form reset

I have a window include a combo like
items: {
xtype: 'form',
items: {
xtype: 'combo',
id: 'combo',
queryMode: 'local',
displayField: 'name',
valueField: 'id',
store: Ext.create('Ext.data.Store', {
fields: ['id', 'name'],
data: [
{'id': '1', 'name': 'John Smith'},
{'id': '2', 'name': 'Albert Einstein'}
]
}),
listeners: {
change: function( combo, newValue, oldValue, eOpts ) {
alert('reset fire 1');
},
dirtychange:function( combo, isDirty, eOpts ) {
alert('reset fire 2');
},
select: function( combo, records, eOpts ) {
alert('reset fire 3');
}
}
}
}
I'm looking for a event inside a combo When i call reset form that will
fire. Is that possible? here is my code http://jsfiddle.net/KVrZ7/
