如何在同一页面上创建此jquery插件的多个实例？

请注意，我在同一页面上创建这个jquery插件的多个实例时遇到了问题。问题是，第一个可以很好地工作，但其他人不能。这是我的代码：

 (function($){
    $.fn.easyPaginate = function (options) { 
    var defaults = {
        paginateElement: 'li',
        hashPage: 'page',
        elementsPerPage: 10,
        effect: 'default',
        slideOffset: 200,
        firstButton: true,
        firstButtonText: '<<',
        lastButton: true,
        lastButtonText: '>>',        
        prevButton: true,
        prevButtonText: '<',        
        nextButton: true,
        nextButtonText: '>'
    }    
    return this.each (function (instance) {    
        var plugin = Object;
        plugin.el = $(this);
        plugin.el.addClass('easyPaginateList');
        plugin.settings = {
            pages: 0,
            objElements: Object,
            currentPage: 1
        }
        var getNbOfPages = function() {
            return Math.ceil(plugin.settings.objElements.length / 
        plugin.settings.elementsPerPage);         
        };
        var displayNav = function() {
            htmlNav = '<div class="easyPaginateNav">';
            if(plugin.settings.firstButton) {
                htmlNav += '<a href="#'+plugin.settings.hashPage+':1" title="First page" rel="1" class="first">'+plugin.settings.firstButtonText+'</a>';
            }
            if(plugin.settings.prevButton) {
                htmlNav += '<a href="" title="Previous" rel="" class="prev">'+plugin.settings.prevButtonText+'</a>';
            }
            for(i = 1;i <= plugin.settings.pages;i++) {
                htmlNav += '<a href="#'+plugin.settings.hashPage+':'+i+'" title="Page '+i+'" rel="'+i+'" class="page">'+i+'</a>';
            };
            if(plugin.settings.nextButton) {
                htmlNav += '<a href="" title="Next" rel="" class="next">'+plugin.settings.nextButtonText+'</a>';
            }
            if(plugin.settings.lastButton) {
                htmlNav += '<a href="#'+plugin.settings.hashPage+':'+plugin.settings.pages+'" title="Last page" rel="'+plugin.settings.pages+'" class="last">'+plugin.settings.lastButtonText+'</a>';
            }

            htmlNav += '</div>';
            plugin.nav = $(htmlNav);
