Creating Infopath forms programmatically - unable to update promoted columns in the library

Question

I referred to the following article and was able to create the forms successfully.
http://www.codeproject.com/Articles/33228/Programmatically-create-a-browser-enabled-InfoPath
But, I noticed that the generated Xml looks a bit different than if I'm creating the document through Sharepoint directly,
for example, a snippet of the generated Xml (through Sharepoint) looks like:
<my:Employee>
          <my:LastName>Test</my:LastName>
          <my:GivenName>Test</my:GivenName>
          <my:EmployeeNumber>1</my:EmployeeNumber>
</my:Employee>
but it looks like the following when I create the document from my C# code:
<Employee>
      <LastName>Test</LastName>
      <GivenName>Test</GivenName>
      <EmployeeNumber>1</EmployeeNumber>
</Employee>
The issue that I'm noticing is that if I chose to publish some of columns (when I publish the form to the sharepoint site) then
the columns will not show the values (I'm guessing that is due to the missing "my" before the fields).
Is there a way to work-around that? or am I doing something incorrect on my side?
Thank you,

Here is a complete method for creating a new infopath form and updating some columns of the new form using sharepoint client object model:
        public string AddNewForm(string WebUrl, string NewTitle)
            string strMsg = "";
            if (string.IsNullOrEmpty(WebUrl))
                return "Empty URL!";
            try
                // Starting with ClientContext, the constructor requires a URL to the server running SharePoint.
                using (ClientContext client = new ClientContext(WebUrl))
                    //client.Credentials = System.Net.CredentialCache.DefaultCredentials;
                    // Assume that the web site has a library named "FormLibrary".
                    var formLib = client.Web.Lists.GetByTitle("FormLibrary");
                    client.Load(formLib.RootFolder);
                    client.ExecuteQuery();
                    // FormTemplate path, The path should be on the local machine/server !
                    string fileName = @"D:\Projects\FormTemplate.xml";
                    var fileUrl = "";
                    //Craete FormTemplate and save in the library.
                    using (var fs = new FileStream(fileName, FileMode.Open))
                        var fi = new FileInfo("newForm.xml");
                        fileUrl = String.Format("{0}/{1}", formLib.RootFolder.ServerRelativeUrl, fi.Name);
                        Microsoft.SharePoint.Client.File.SaveBinaryDirect(client, fileUrl, fs, true);
                        client.ExecuteQuery();
                    // Now we are going to update new form fields.
                    // Get library columns collection.
                    var libFields = formLib.Fields;
                    client.Load(libFields);
                    client.ExecuteQuery();
                    Microsoft.SharePoint.Client.File newFile = client.Web.GetFileByServerRelativeUrl(fileUrl);
                    ListItem item = newFile.ListItemAllFields;
                    // Here the index of Title column is 9, you may use this form to update any column (even promoted fields).
                    // To find the index of interested column you should inspect libFields at debug mode, look in the libFields.Fields collection to find the index!
                    item[libFields[9].StaticName] = NewTitle ;
                    item.Update();
                    client.ExecuteQuery();
            catch (Exception ex)
                strMsg = ex.Message;
            return strMsg;
