Accessing fontstring from secure snippet

Hello. I'm trying to implement simple raid frames. Here's what I've come up with so far:

XML Code:
  1. <Ui xmlns="http://www.blizzard.com/wow/ui/">
  2.   <Frame name="MyFrames_UnitTemplate" inherits="SecureUnitButtonTemplate" virtual="true">
  3.     <Size x="36" y="36"/>
  4.     <Layers>
  5.       <Layer level="OVERLAY">
  6.         <Texture>
  7.           <Color r="0" g="0" b="0"/>
  8.         </Texture>
  9.         <FontString parentKey="name" inherits="GameFontHighlight" text="Name"/>
  10.       </Layer>
  11.     </Layers>
  12.     <Attributes>
  13.       <Attribute name="type1" type="string" value="target"/>
  14.     </Attributes>
  15.   </Frame>
  17.   <Frame name="MyFrames_SecureGroupTemplateHeader" parent="UIParent" inherits="SecureGroupHeaderTemplate">
  18.     <Anchors>
  19.       <Anchor point="TOP"/>
  20.     </Anchors>
  21.     <Attributes>
  22.       <Attribute name="showParty" type="boolean" value="true"/>
  23.       <Attribute name="showRaid" type="boolean" value="true"/>
  24.       <Attribute name="showPlayer" type="boolean" value="true"/>
  25.       <Attribute name="showSolo" type="boolean" value="true"/>
  26.       <Attribute name="maxColumns" type="number" value="8"/>
  27.       <Attribute name="unitsPerColumn" type="number" value="5"/>
  28.       <Attribute name="columnAnchorPoint" type="string" value="TOP"/>
  29.       <Attribute name="point" type="string" value="LEFT"/>
  30.       <Attribute name="template" type="string" value="MyFrames_UnitTemplate"/>
  31.       <Attribute name="templateType" type="string" value="Button"/>
  32.       <Attribute name="columnSpacing" type="number" value="1"/>
  33.     </Attributes>
  34.   </Frame>
  35. </Ui>
Lua Code:
  1. MyFrames_SecureGroupTemplateHeader:SetAttribute("initialConfigFunction", [=[
  2.   print("icf", self:GetName())
  3.   self:SetAttribute("refreshUnitChange", [[
  4.     print("ruc", self:GetName(), self:GetAttribute("unit"))
  5.     --self.name:SetText(UnitName(self:GetAttribute("unit")))
  6.   ]])
  7. ]=])
  9. MyFrames_SecureGroupTemplateHeader:Show()

It works with static label, but I'm struggling to set name dynamically. I've commented line that does not work. As far as I understood, self refers to frame handle and this frame handle does not have "name" key (which I expected to be set from XML parentKey attribute). I tried to use self:GetFrameRef("name"), but it returns null. I guess I have to register it earlier, but I can't figure out how do I do that. UnitName is not available either, so I'm further confused atm. I guess, I'm doing something seriously wrong. If possible, I prefer to keep XML for UI layouts instead of coding it all with Lua. Also, if possible, it should work in combat (so people entering/leaving raid won't brake frames, that's why I'm using SecureGroupHeaderTemplate).
