Resources and ContentControl templates

When setting a contentcontrols template to xaml in code behind I cant access a static resource contained in the parent xaml.

I have a contentcontrol as follows:

<ContentControl x:Name="ccMaterial"><ContentControl.Resources><x:Array x:Key="BondListKey"Type="sys:Int32"
             xmlns:sys="clr-namespace:System;assembly=mscorlib"/></ContentControl.Resources></ContentControl>

then in codebehind I am setting the template as follows:

string template ="<ControlTemplate xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'>"+"<ComboBox Grid.Column=\"1\" Grid.Row=\"0\" ItemsSource=\"{Binding Source={StaticResource BondListKey}}\"  />"+"</ControlTemplate>";
ccMaterial.Template=(ControlTemplate)XamlReader.Parse(template);

The problem is that when i try to run this I get the exception saying that the resource "BondListKey" cannot be found. Can anyone explain why?

Please let me know if you need anymore information.
