Bootstrap自定义ajax模式

Question

参考this主题，我创建了ajax模式：

MAIN JS FILE
(function ($)
{

    $.fn.ajaxmodal = function (options)
    {
        var defaults = {
            title: "", 
            content: $("<p />"),
            id: "ajaxmodal", 
            open: function () { }, 
        };
        var settings = $.extend(true, {}, defaults, options);

        if (settings.js){
            var js = document.createElement("script");
            js.id = "script"+settings.id;
            js.type = "text/javascript";
            js.innerHTML += settings.js;        
        }
        if (settings.css){
            var css = document.createElement("style");
            css.id = "style"+settings.id;
            css.type = "text/css";
            css.innerHTML += settings.css;      
        }       
        // create the DOM structure
        var $modal = $("<div />").attr("id", settings.id).attr("role", "dialog").addClass("modal fade").attr("data-keyboard", "false").attr("data-backdrop", "static")
                        .append($("<div />").addClass("modal-dialog")
                            .append($("<div />").addClass("modal-content")
                                .append($("<div />").addClass("modal-header")
                                    .append($("<h4 />").addClass("modal-title").text(settings.title)))
                                .append($("<div />").addClass("modal-body")
                                    .append(settings.content))
                            )
                        );
        $modal.shown = false;
        this.dismiss = function ()
        {
           if (!$modal.shown)
            {
                window.setTimeout(function ()
                {
                    $modal.dismiss();
                }, 50);
                return;
            }
            $modal.modal("hide");
            $modal.prev().remove();
            $modal.empty().remove();
            $("body").removeClass("modal-open");
            if (settings.js){ $("#script"+settings.id).remove(); }
            if (settings.css){ $("#style"+settings.id).remove(); }
        }
        $modal.find(".modal-header").prepend($("<button />").attr("type", "button").addClass("close").html("&times;").click(function () { $modal.dismiss() }));
        settings.open($modal);

        $modal.on('shown.bs.modal', function (e) {
            $modal.shown = true;
            if (settings.js){ $("body").append(js); }
            if (settings.css){ $("body").append(css); }
        });
        $modal.modal("show");       

        return $modal;
    };
})(jQuery);

我通过jq / php加载内容

MAIN JS FILE:
    $(document).on('click', '.open_modal', function() {
        var a = 'my..vars...';
        $.post("/ajax_modal.php", a, function(o){
            if(o.s){
                 // open modal
                $.fn.ajaxmodal(o.o);

            } else {
                 // invalid access
                $.notify(o.m);
            }
        },'json');  
    }); 

AJAX.PHP:
            $obj = array(
                'title' => 'My title',
                'content' => '

            <div class="box">
                <button type="button" class="btn clickme">Button</button>
            </div>
            <div class="box2">          
                content
            </div>              

                ',
                'id' => 'modal-'.$id,
                'js' => '
$(document).on("click", ".clickme", function() {
    var a = "my..vars..";
    $.post("/ajax_modal.php", a, function(o){
        if(o.s){
            //  
            //      PROBLEM
            //
            $.fn.ajaxmodal.dismiss;
            $.notify(o.m);
        } else {
            // dismiss modal
            $.notify(o.m);
        }
    },"json"); 
}); 

                        ',
                'css' => '
.box {display: block; width: 100%;}
                '

                );

            $out = array(
                's'=>1,
                'o'=>$obj
            );
            echo json_encode($out);

通过ajax我创建模态并注入内容和CSS＆amp; JS进入正文，问题是关闭模态的函数不起作用（$ .fn.ajaxmodal.dismiss;或$ .fn.ajaxmodal.dismiss（）;不起作用）关闭模态并从正文中删除内容和脚本。我试过了

IN MAIN JS
            if(o.s){
                var ajax_mod = $.fn.ajaxmodal(o.o);

            } else {    

AND IN ajax.php
        if(o.s){
            ajax_mod.dismiss();
//          OR
//          ajax_mod.dismiss;
            $.notify(o.m);
        } else {

但那也不起作用..我怎样才能做到这一点？
