Wp 8.1 and trigger - windows-runtime

Question

I've developed app on windows phone 8 with caliburn. On one of my pages, I have a button inside of a datatemplate and I have set trigger on mouse click:
<DataTemplate>
<Button>
<i:Interaction.Triggers>
<i:EventTrigger EventName="Click">
<micro1:ActionMessage MethodName="GoToPage">
<micro1:Parameter Value="{Binding Path=PageId}" />
</micro1:ActionMessage>
</i:EventTrigger>
</i:Interaction.Triggers>
<TextBlock Text="{Binding Path=PageDescription}" TextWrapping="Wrap"
HorizontalAlignment="Center" VerticalAlignment="Center" />
</Button>
</DataTemplate>
It works fine.
Now I've created new app on windows phone 8.1 (winrt), but with same code I've an error on trigger. How i can do it on wp 8.1 ? I have found winrttriggers.codeplex.com but it isn't compatible with wp 8.1 platform.
Thanks a lot!
EDIT 1:
With your code my view doesn't fire command.
Now I have:
<i:Interaction.Behaviors>
<core:EventTriggerBehavior EventName="Click">
<core:InvokeCommandAction Command="{Binding OpenPageCommand}" CommandParameter="{Binding Path=PageId}" />
</core:EventTriggerBehavior>
</i:Interaction.Behaviors>
My command is delegate command:
public class DelegateCommand<T> : ICommand
{
private readonly Func<T, bool> _canExecuteMethod;
private readonly Action<T> _executeMethod;
#region Constructors
public DelegateCommand(Action<T> executeMethod)
: this(executeMethod, null)
{
}
public DelegateCommand(Action<T> executeMethod, Func<T, bool> canExecuteMethod)
{
_executeMethod = executeMethod;
_canExecuteMethod = canExecuteMethod;
}
#endregion Constructors
#region ICommand Members
public event EventHandler CanExecuteChanged;
bool ICommand.CanExecute(object parameter)
{
try
{
return CanExecute((T)parameter);
}
catch { return false; }
}
void ICommand.Execute(object parameter)
{
Execute((T)parameter);
}
#endregion ICommand Members
#region Public Methods
public bool CanExecute(T parameter)
{
return ((_canExecuteMethod == null) || _canExecuteMethod(parameter));
}
public void Execute(T parameter)
{
if (_executeMethod != null)
{
_executeMethod(parameter);
}
}
public void RaiseCanExecuteChanged()
{
OnCanExecuteChanged(EventArgs.Empty);
}
#endregion Public Methods
#region Protected Methods
protected virtual void OnCanExecuteChanged(EventArgs e)
{
var handler = CanExecuteChanged;
if (handler != null)
{
handler(this, e);
}
}
#endregion Protected Methods
}
On my view model I have:
public ICommand OpenPageCommand { get; set; }
on constructor:
OpenPageCommand = new DelegateCommand<Guid>(GoToPage);
and my methods is:
public void GoToPage(Guid pageId)
{ .....
but it does not work. Any idea?
Thanks so much!

You should be able to do this with the Behaviors SDK. Include this namespaces:
xmlns:i="using:Microsoft.Xaml.Interactivity"
xmlns:core="using:Microsoft.Xaml.Interactions.Core"
And than you should be able to trigger a command like this:
<i:Interaction.Behaviors>
<core:EventTriggerBehavior EventName="Click">
<core:InvokeCommandAction Command="{Binding GoToPage}" CommandParameter="{Binding Path=PageId}" />
</core:EventTriggerBehavior>
</i:Interaction.Behaviors>
