2 つの入力を Google オートコンプリートで入力してから、Google マップのルート案内を取得しようとしています。

なんとかオートコンプリートを使用できましたが、送信ボタンをクリックしても何も起こりません。

私はこのコードを使用しています：

function initialize() {
    map = new GMap2(document.getElementById("map_canvas"));
    map.setCenter(new GLatLng(39.57182223734374, -7.811279296875), 15);
    gdir = new GDirections(map, document.getElementById("directions"));

    var input = document.getElementById('tb_fromPoint');
    var autocomplete = new google.maps.places.Autocomplete(input);

    var input2 = document.getElementById('tb_endPoint');
    var autocomplete2 = new google.maps.places.Autocomplete(input2);

    setDirections();

}

function setDirections() {
    var fromAddress = document.getElementById('tb_fromPoint');
    var toAddress = document.getElementById('tb_endPoint');
  gdir.load("from: " + fromAddress + " to: " + toAddress,  { "locale": "pt_PT" });

}

google.maps.event.addDomListener(window, 'load', initialize);
