ajax遍历出来的数据取不到元素

success: function (data) {
        if (data == null) {
            return false;
        }
        var tbody=$("#tbody");
        list = data.object;
        $.each(list, function (index, value) {
            var b="";
            var energize;
            var blackout;
            if(value.energize==null){
                energize="";
            }
            if(value.blackout==null){
                blackout="";
            }
            b+="<tr>"
            b+="<td class='id'>"+value.id+"</td>";
            b+="<td class='orderid'>"+value.orderid+"</td>";
            b+="<td class='type'>"+value.type+"</td>";
            b+="<td class='power'>"+value.power+"</td>";
            b+="<td class='num'>"+value.num+"</td>";
            b+="<td class='energize'>"+energize+"</td>";
            b+="<td class='blackout'>"+blackout+"</td>";
            b+="<td class='createtime'>"+value.createtime+"</td>";
            b+="<td><button type='button' class='btn btn-primary energize'>通电</button><button class='btn btn-primary blackout' >断电</button></td>"
            b+="<td><button type='button' class='btn btn-primary update'>修改</button><button class='btn btn-primary del'>删除</button></td>"
            b+="</tr>"
            tbody.append(b);
        })
    },

            这是遍历数据

            然后
            $(".energize").click(function () {
    debugger;
    var id=$("#id").val();
    console.log("1")
    $.ajax({
        url: 'jh/order/energize',
        type:"post",
        contentType: "application/json",
        dataType: "text",
        data: { 'id':id},
        success: function (data) {
            if (data = null) {
                return false;
            }

            window.location.reload();
            console.log(data);
        },
        error: function (data) {
            console.log(data)

        }
    })
            这个方法触发不了

动态元素的原因
$(".energize").click(function () {
改为
$(document).on('click','.energize',function(){
