How to fix a infowindow or a info template to a point so that when i drag the map the infowindow will no change place or move ...what is the code...and where shld i place it at?

this is my code :
var stX = "23319.3347409758";
var stY = "28825.7191286444";
var pt= new esri.geometry.Point(stX,stY,map.spatialReference);
//var strImage = "";
var symbol = new esri.symbol.PictureMarkerSymbol(strImage, 25,25);
var attr = {"PlaceName":"Peranakan musem of Singapore","PlaceAddr":"addr"};
var infoTemplate = new esri.InfoTemplate();
infoTemplate.setTitle("Building Name:");
var graphic = new esri.Graphic(pt,symbol,attr,infoTemplate);

function getInfoContent(graphic){
var bc = new dijit.layout.BorderContainer({style: "font-size: 11pt; height: 520px; width:493px; background: #CCFFFF;"});
var c1 = new dijit.layout.ContentPane({
region: "top",
style: "height: 20px width: 100%",
content: "hello"

//make a tab container
var tc = new dijit.layout.TabContainer({
region: "center",
style: "height: 65%; width: 100%; "
}, dojo.create("div"));

//display attribute information
var cp1 = new dijit.layout.ContentPane({
//style: " background-color: red; ",
title: "<font color= #E4287C><b>detail</font> ",
content: "sfdfsdfsdf"
return bc.domNode;
