Tridion: Component Template issue when looping over linked components

Question

Hello, I got a problem with looping over my linked component.
I created a EmailSetup(View UML diagram) Component with a product item.
The product Component has schema (EmailBlockWithCode).
Product:

• - Code = "wms_III"
• - Item:
• - Key = "ProductKey"
• - Content = "ProductContent"
• - CallToAction :
  • - Item:
    • - Key = "BluetoothKey"
    • - Content = "BluetoothContent"

When i loop over this component with the code :

  <products>
            <!-- TemplateBeginRepeat name="Component.Fields.Product" -->
            @@GetComponent(Field,'Product')@@
            <product name="@@Product.Code@@">   
              <!-- TemplateBeginRepeat name="Product.Fields.Item" -->
                <@@Product.Fields.Item.Key@@><![CDATA[@@Product.Fields.Item.Content@@]]></@@Product.Fields.Item.Key@@>
              <!-- TemplateEndRepeat -->
              <!-- TemplateBeginRepeat name="Product.Fields.CallToAction" -->
                @@GetComponent(Field,'CallToAction')@@
                <@@CallToAction.Fields.Item.Key@@><![CDATA[@@CallToAction.Fields.Item.Content@@]]></@@CallToAction.Fields.Item.Key@@>
              <!-- TemplateEndRepeat -->    
            </product>
         <!-- TemplateEndRepeat -->
    </products>

This is the function GetComponent

[TemplateCallable]
        public string GetComponent(string tcmUri, string packageVariable) {
            Assert.NotEmpty("tcmUri", tcmUri);
            Assert.NotEmpty("packageVariable", packageVariable);
            IdentifiableObject identifiableObject = m_Engine.GetObject(new TcmUri(tcmUri));

            if (identifiableObject as Component == null) {
                throw new BuildingBlockException("Given tcmUri '" + tcmUri + "' is not a Component.");
            }

            Item previousItem = m_Package.GetByName(packageVariable);
            if (previousItem != null) {
                m_Package.Remove(previousItem);
            }
            Component component = identifiableObject as Component;
            m_Package.PushItem(packageVariable, m_Package.CreateTridionItem(ContentType.Component, component));
            return "";
        }

My output is :

<products>
        <product name="wms_III">    

        </product>
    </products>

So my problem is that the code doesn't loop
over the 'item' (key = ProductKey; content = ProductContent) I have found a function IteratingOverMultivalueEmbeddedFields but this also won't loop my product. code:

<!-- TemplateBeginRepeat name="Component.Fields.Product" -->
            @@GetComponent(Field,'Product')@@
       <!-- TemplateBeginRepeat name="Product.Fields" -->
  @@Field.Name@@
  <!-- TemplateBeginRepeat name="Field.Values" -->
    <!-- TemplateBeginIf cond="Field.ContentType = 'text/plain'" -->      
    @@RenderComponentField(FieldPath, TemplateRepeatIndex)@@
    <!-- TemplateEndIf -->
    <!-- TemplateBeginIf cond="Field.ContentType = 'tridion/field'" -->
      <!-- TemplateBeginRepeat name="Field.Fields" -->
        @@Field.Name@@
        <!-- TemplateBeginRepeat name="Field.Values" -->
          @@RenderComponentField(FieldPath, TemplateRepeatIndex)@@        
        <!-- TemplateEndRepeat -->
      <!-- TemplateEndRepeat -->
    <!-- TemplateEndIf -->
  <!-- TemplateEndRepeat -->
<!-- TemplateEndRepeat -->

I fixed this by using this code. Not the best but it works.

<products>
        <!-- TemplateBeginRepeat name="Component.Fields.Product" -->
            @@RenderComponentPresentation(Field, "tcm:75-72162-32")@@
        <!-- TemplateEndRepeat -->
</products>

and the renderComponentPresentation loads another dwt with this:

 <product name="@@Component.Fields.Code@@">
          <!-- TemplateBeginRepeat name="Component.Fields.Item" -->
              <@@Field.Key@@><![CDATA[@@Field.Content@@]]></@@Field.Key@@>
          <!-- TemplateEndRepeat -->
          <!-- TemplateBeginRepeat name="Component.Fields.CallToAction" -->
              @@GetComponent(Field,'CallToAction')@@
              <@@CallToAction.Fields.Item.Key@@><![CDATA[@@CallToAction.Fields.Item.Content@@]]></@@CallToAction.Fields.Item.Key@@>
          <!-- TemplateEndRepeat -->    
      </product>
