I use yui datatable in my asp.net application... I have a link button in one of my columns and it works fine but doesn't do a postback of a hidden button...

 myDataTable.subscribe("linkClickEvent", function(oArgs) {
            javascript: __doPostBack('ctl00_ContentPlaceHolder1_Button1', '');
            YAHOO.util.Event.stopEvent(oArgs.event);
        });

and in my page

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button"
   style="display:none;" />

 protected void Button1_Click(object sender, EventArgs e)
 {
    DownloadFile(Hfhref.Value, true);
 }

I used break point but it doesn't seem to get the __dopostback.. Any suggestion...
