sencha怎么在control层调用按钮

暂时在这里总结了3种方法：

config: {
refs: {
sendMaint: 'sendMaint',
basicinfolist:'basicinfolist',
refreshButton: '#bill_refreshButon',
},
control: {
refreshButton: {
tap: 'onRefreshBill'　　　　　　 // id: 'bill_refreshButton',
},
basicinfolist:{
viewDrawCommand: 'onSelHistory'　　　//this.fireEvent('viewDrawCommand', record);
},
'sendMaint searchfield[action=cx]': {　　　//xtype:searchfield,action:cx
change: 'onSelectChange2duox'
},
'sendMaint button[action=onSaveBtn]' : {　　//xtype:button,action:onSaveBtn
tap : 'onSaveBtn'
}

}
