Changing ListBox feeds into Pivot (SyndicationItem message instead of text) - windows-phone-7

Question

So, I found a way of creating RSS feed app for Windows Phone. It binds SyndicationFeed items into Listbox template. And it works great!
However, I wanted to make an app, that handles a bit different. I thought, that changing Listbox template into Pivot would be quite easy. The problem is, that instead of articles I get only "System.ServiceModel.Syndication.SyndicationItem".
I am out of ideas how to fix that, could anyone help me?

}
There are some "leftovers" for handling another actions. Please ignore them, I didn't get to it yet. The biggest focus is to make it show text after app is loaded.

I bealive that I fixed that. There was a problem with Pivot concept. This is how I fixed that:
<controls:Pivot Name="FeedPivot" Loaded="loadFeed" ScrollViewer.VerticalScrollBarVisibility="Visible" Tap="feedPivotTap" Margin="0,88,0,0" LoadedPivotItem="getPivotItem">
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock FontWeight="Bold" FontSize="28" Name="feedTitle" TextWrapping="Wrap" Margin="12,0,0,0" HorizontalAlignment="Left" Foreground="#FF5DBA00" Text="{Binding Title.Text, Converter={StaticResource RssTextTrimmer}}" Width="430" />
</DataTemplate>
</controls:Pivot.HeaderTemplate>
<controls:Pivot.ItemTemplate>
<DataTemplate>
<ScrollViewer>
<StackPanel>
<TextBlock Name="feedSummary" FontSize="24" TextWrapping="Wrap" Margin="12,0,0,0" Text="{Binding Summary.Text, Converter={StaticResource RssTextTrimmer}}" Width="430" />
<TextBlock Name="feedPubDate" Foreground="{StaticResource PhoneSubtleBrush}" Margin="12,0,0,10" Text="{Binding PublishDate.DateTime}" Width="430" />
</StackPanel>
</ScrollViewer>
</DataTemplate>
</controls:Pivot.ItemTemplate>
</controls:Pivot>
