In your case, you do not need to use ajax to change address of Google Map on WebBrowser.
So, could you please try my Steps as below?

1. create new RPCL form app
2. add GoogleMap and Button component on the form
3. change ButtonType property from btSubmit to btNormal
4. just add OnClick Javascript event for Button component as below
-----------------
class Unit1 extends Page
{
    public $GoogleMap1 = null;
    public $Button1 = null;
    function Button1JSClick($sender, $params)
    {
        ?>
        //begin js
        var map = new GMap2(document.getElementById('GoogleMap1_div'));
        var geocoder = new GClientGeocoder();
        var address="Belo Horizonte, MG";
        geocoder.getLatLng(address,
          function(point) {
            if(point) {
              map.setCenter(point, 13);
              var marker = new GMarker(point);
              //map.addOverlay(marker);
              marker.openInfoWindowHtml(address);
            }
          }
        );
        //end
        <?php
    }
}
