i have a control template define like the one below . Inside the ControlTemplate there is ChatEntry control named "txtchatmessage" and a TextChanged event handler named txtchatmessage_TextChanged and Focus , when i enter text this even does not get fired

 private void Txtchatmessage_TextChanged(object sender, TextChangedEventArgs e) 

{ 

//my logic 

} 

<ControlTemplate x:Key="CustomChatControlTemplate"> 

<Grid telerikInput:KeyboardHelper.IsTranslationTarget="True"  

RowSpacing="2"> 

<Grid.RowDefinitions> 

<RowDefinition /> 

<RowDefinition Height="Auto" /> 

</Grid.RowDefinitions> 

<Image HorizontalOptions="FillAndExpand" x:Name="ctr1" VerticalOptions="FillAndExpand" Aspect="AspectFill" Source="chat_background.png" /> 

 

<Grid Grid.Row="2" Padding="5, 0, 0, 0"> 

<Grid.ColumnDefinitions> 

<ColumnDefinition Width="Auto" /> 

</Grid.ColumnDefinitions> 

 

<StackLayout Orientation="Vertical" BackgroundColor="White" > 

<StackLayout Orientation="Horizontal" BackgroundColor="Transparent"> 

<telerikConversationalUI:ChatEntry x:Name="txtchatmessage" Keyboard="Chat" TextChanged="txtchatmessage_TextChanged"  

HorizontalOptions="StartAndExpand" WidthRequest="280" 

telerikInput:KeyboardHelper.IsTranslationSource="True" /> 

 

<StackLayout Orientation="Horizontal">
