<div class="fb-login-button"  data-width="200" onlogin="GetData()"></div>
<script>
                window.fbAsyncInit = function () {
                FB.init({
                        appId: 'My ID',
                        status: false,
                        cookie: true,
                        xfbml: true,
                        oauth: true
                });
                };        
                (function (d) {
                var js, id = 'facebook-jssdk'; if (d.getElementById(id)) { return; }
                js = d.createElement('script'); js.id = id; js.async = true;
                js.src = "//connect.facebook.net/en_US/all.js";
                d.getElementsByTagName('head')[0].appendChild(js);
                } (document));

Answer 1

Call this function for facebook login your GetData function called after user logged .

function facebooklogin(){

  FB.login(function(response) {
     if (response.authResponse) {
             GetData();
        });

        }
