[jQuery] what wrong in code?

[R.O.M.]

This code doesn't work in all browsers exept firefox. Why and what i
must to do?
Trouble: when button with id="newsitesubmit" was pressed there is no
reaction, but in firefox all is ok.

code:

function getready() {
  $('#newsitesubmit').click(sendsite);
 };

function sendsite() { /* отправляем данные из формы */
   getready();
   var sitename = $("#siteinfo #sitename").val();
   var siteurl =  $("#siteinfo #siteurl").val();
   var uname = $("#siteinfo #username").val();
   var uemail =  $("#siteinfo #uemail").val();
   $.get('savesite.cgi', {sname: sitename, surl: siteurl, uname:
uname, uemail:
   $.get('static/msg_site_added.txt',function(data){
     var oldcontent = $('#siteinfo').html();
     $('#siteinfo').html(data+'Добавить еще сайт');
     getready();
    }
   );

html:

 <div id="add">

<h4>Добавление сайта</h4><br>
<form id="newsite">
<dl>
 <dt><label for="form-sitename">Название:</label></dt>
 <dd><input type="text" name="sitename" id="sitename"></dd>
 <dt><label for="form-siteurl">Адрес:</label></dt>
 <dd><input type="text" name="siteurl" id="siteurl"></dd>

 <dt><label for="form-username">Ваше имя:</label></dt>
 <dd><input type="text" name="username" id="username"></dd>
 <dt><label for="form-useremail">Ваш e-mail:</label></dt>
 <dd><input type="text" name="uemail" id="uemail"></dd>
 <dd><input type="button" value="Отправить" id="newsitesubmit"></dd>
