自定义事件多次执行问题

今天才发现的一个奇怪问题，从主页面打开一个预加载页面，点击的时候添加自定义事件，进入列表页，列表页监听点击添加的自定义事件刷新数据，在列表页的监听事件函数中写点击事件，会随着主页面进入列表页次数的增加而增加，请问是什么原因。代码大概是下面这样的

//首页代码  
(function($) {  
    var localBusiness_view;  
    var hotel_searcHotel_view;  
    $.plusReady(function() {  
        if (!hotel_searcHotel_view) {  
            hotel_searcHotel_view = $.preload({  
                url: 'page/hotel_searcHotel.html',  
                id: "hotel_searcHotel",  
                waiting: {  
                    autoShow: false  
                }  
            });  
        }  
        if (!localBusiness_view) {  
            localBusiness_view = $.preload({  
                url: 'page/localBusiness.html',  
                id: "localBusiness",  
                waiting: {  
                    autoShow: false  
                }  
            });  
        }  
    });  
    $("#list1").on("tap", ".webkitbox", function() {  
        var dataIt = this.getAttribute("data-item");  
        if (dataIt == "1") {  
            var type = this.getAttribute("data-type");  
            $.fire(localBusiness_view, "localBusiness_view", {  
                type: type  
            });  
            localBusiness_view.show("pop-in");  
        } else {  
            $.fire(hotel_searcHotel_view, "hotel_searcHotel_view", {});  
            hotel_searcHotel_view.show("pop-in");  
        }  
    });  
})(mui);  
//列表页代码  
window.addEventListener("localBusiness_view", function(event) {  
    (function($) {  
        $('#temp').on('tap', 'li', function(event) {  
            console.log(">>>>>>>>>>>>>>>");  
            var loc = this.getAttribute("data-url");  
            localStorage.setItem("baiduurl", loc);  
            var baidu = plus.webview.create("localbusinessbaidu.html", "localbusinessbaidu");  
            baidu.show("pop-in");  
        });  
    })(mui);  
})
