its the HtmlForm control that renders client script, so if you do not have
one, it will not render. if you are not using forms, then you can use the
asp:placeholder and the HtmlGeneric control to output script.
HtmlGenericControl myScript = new HtmlGenericControl("script");
myScript.InnerText = "alert('hi')";
myScriptPlaceHolder.Controls.Add(myScript);
