Dynamic select

I am trying to customize link.js plugin to generate dynamic items for select element. But i am facing with problems,

 children: [{
                        id: "pages",
                        type: "select",
                        items: pageItems(),

I write a function to generate items for select element and assign it (items: pageItems(),)

The function is;

function pageItems() {
        var pageArray = [];
        var obj = {};
        $("#pageItems li").each(function () {
            /*alert($(this).text());*/
            var obj = {};
            obj[$(this).text()] = $(this).text();
            pageArray.push(obj);

        });
        var JSONText = JSON.stringify(pageArray, null);
        JSONText = JSONText.replace(/{/g, "[");
        JSONText = JSONText.replace(/}/g, "]");
        JSONText = JSONText.replace(/:/g, ",");
        alert(JSONText);
        return pageArray;
    }

First i return directly pageArray but in select all options are undefined. After i serialize pageArray to JSON array but this time a get diffrent problems;

The JSON array is look like; 

[["/main/23/hakkimizda","/main/23/hakkimizda"],["/main/24/iletisim","/main/24/iletisim"]]

and the select result is;
