mui事件绑定

                    mycar += '<li class="mui-table-view-cell" data-id="'+i+'">'  
                          +  '<div class="mui-table">'  
                          +  '<div class="mui-table-cell mui-col-xs-10">'  
                          +  '<label>车的名称:&emsp;'+list.CAR_NAME+'</label><br />'    
                          +  '<label>车牌号码:&emsp;'+list.CAR_NUMBER+'</label><br />'      
                          +  '<label>车的型号:&emsp;'+list.CAR_MODEL+'</label>'  
                          +  '<h4>'     
                          +     '<button id="delete" type="button" class="mui-btn" style="float: right;margin-right: 1%;" onclick="delCar('+list.CAR_ID+')">删除</button>'  
                          +     '<button type="button" id="updatecar" class="mui-btn mui-btn-danger" style="float: right;margin-right: 5%;background-color: #FF999A;border: 0 solid;">修改</button>'    
                          +     '</h4>'  
                          + '</div>'  
                    +   '</div>'  
                  + '</li>'  

mui('#myCarContent').on('tap','li',function(){ }); 怎么把事件分别绑定到删除按钮 修改按钮上。
