Scene Graph LabelList

Hello, I’m Creating an App for Roku with Scene Graph Framework. I got problem at the beginning. When I create LabelList and download it to my Roku Stick, I press Up and Down buttons and nothing happens – list doesn’t update. Here’s my code(took from http://sdkdocs.roku.com/display/sdkdoc/ContentNode#ContentNode-Description)

<?xml version="1.0" encoding="utf-8" ?>

<component name="labelScene" extends="Scene" >

<script type="text/brightscript" >
<![CDATA[
 
sub init()
  m.list = m.top.FindNode("coreList")
 
  m.content = createObject("RoSGNode","ContentNode")
 
  addSection("Renderable Nodes")
  addItem("Rectangle")
  addItem("Rotated Rectangle")
  addItem("Label")
  addItem("Poster")
  addItem("Video")
  addItem("Video Zoom")
 
  addSection("Animation Nodes")
  addItem("Animation Vector 2D Interpolator")
  addItem("Animation Color Interpolator")
  addItem("Animation Float Interpolator")
  addItem("Sequential Animation")
  addItem("Parallel Animation")
  addItem("Fade-In Animation")
  addItem("Fade-Out Animation")
 
  addSection("Control Nodes")
  addItem("Timer")
 
  addSection("Lists and Grids")
  addItem("Poster Grid")
  addItem("Markup Grid")
 
  m.list.content = m.content
  m.list.ObserveField("itemFocused", "printing")
  m.top.setFocus(true) 
end sub
 
sub printing()
	print "Hello"
end sub
 
sub addSection(sectiontext as string)
  m.sectionContent = m.content.createChild("ContentNode")
  m.sectionContent.CONTENTTYPE = "SECTION"
  m.sectionContent.TITLE = sectiontext
end sub
 
sub addItem(itemtext as string)
  item = m.sectionContent.createChild("ContentNode")
  item.title = itemtext
end sub
]]>
</script>
 <children>
<LabelList
  id="coreList"
  translation="[160,92]"
  itemSize="[440,48]"
  itemSpacing="[0,0]"
  sectionDividerHeight="48.0"
  sectionDividerFont="font:MediumBoldSystemFont"
  sectionDividerTextColor="0x880088FF"
  drawFocusFeedback="true"	/>
 </children>
</component>

Documentation says that Lists automatically response Key-pressings and so on

Sorry, It was my mistake. All I needed was just to set the right focus.
