how to only get title of subsite and not display title of app also

right now this code writes out the subsites title and relativeurl, but it also includes my title of my app, but i only want to display the subsites title and not title of the app also,

Any sugesstions what i should do? Here is my code

 function execCrossDomainRequest() {
        var executor = new SP.RequestExecutor(appweburl);
        var queryUrl = appweburl + "/_api/SP.AppContextSite(@target)/web/webs?$select=Title,ServerRelativeUrl&@target='" +hostweburl + "'" ;

        executor.executeAsync(
             {
                 url: queryUrl,
                 method: "GET",
                 headers: { "Accept": "application/json; odata=verbose" },
                 success: successHandler,
                 error: errorHandler
             }
                 );
                    }
                        })
function successHandler(data) {
$("#subSiteTitle").keypress(function () {
    var jsonObject = JSON.parse(data.body);
    var dataArr = $.makeArray(jsonObject.d.results);
    var resultArr = $.map(dataArr, function (item) {

        return { label: item.Title + " (" + item.ServerRelativeUrl + ")", value: item.ServerRelativeUrl };

    });
