SharePoint 2010 - Assign value to a hidden field from javascript function on content master page

Hi,
I tried to store the output of a javascript function (Func() in my case) to a HiddenField in the SharePoint Master Page but the value that is assigned to the "Value" property of the hidden field is displayed as it is.
My code is,

(.master file)

ASP.NET

<head>
<script>
     function Func()
     {
     var msg="Hello";
     return msg;
     }
</script>
</head>

<body>
<form id="form1" runat="server">
<div>
 <asp:HiddenField ID="HidFieldID"; runat="server"; Value="Func()" />
 </div>
</form>
</body>

In the above code, I have called the javascript function in the Value property of HiddenField. And my code behind (C#) is,

HiddenField lblHTMLHiddenField = (HiddenField)this.Page.Master.FindControl("HidFieldID");
if (lblHTMLHiddenField != null)
{
  Label1.Text = lblHTMLHiddenField.Value;
}

The hidden field in the master page is called but the value assigned to the label is "Func()" given in the Value property and not the result of Func().

Please help me to store the output of the function in the hidden field.

Thanks in advance.

Value is just a string, so it does not get executed. You just need to call the code somewhere and fill in the value.
