Can i remove and add command on GestureRecognize? - xamarin.forms

Question

i have a page where user can swap labels. So I have a ExtendedWebView CZ and ExtendedWebView EN once user presses button i need them to swap. I have decided to swap these ExtendedWebView in the bac of my page as that seemed much easier however both these commes with button that each fires different pop up. So if i swap ExtendedWebView CZ i need the button that fires CZ pop up to be swapped also.
This is how i am changing my ExtendedWebViews
bool isSwap = false;
private void ChangePosition(object sender, EventArgs e)
{
isSwap = !isSwap;
czView.RemoveBinding(ExtendedWebView.SourceProperty);
enView.RemoveBinding(ExtendedWebView.SourceProperty);
if (isSwap)
{
btnChangePositions.Text = "EN/CZ";
czView.SetBinding(ExtendedWebView.SourceProperty,("EN"));
enView.SetBinding(ExtendedWebView.SourceProperty, ("CZ"));
}
else
{
btnChangePositions.Text = "CZ/EN";
czView.SetBinding(ExtendedWebView.SourceProperty, ("CZ"));
enView.SetBinding(ExtendedWebView.SourceProperty, ("EN"));
}
}
Xaml
<Label
x:Name="makeLargerEN"
FontFamily="{StaticResource IconsFontFamily}"
HorizontalTextAlignment="End"
Text="{Binding MakeLargerEN}"
TextColor="{DynamicResource AccentColor}"
VerticalTextAlignment="End">
<Label.GestureRecognizers>
<TapGestureRecognizer Command="{Binding MakeWebViewLargeEnCommand}" />
</Label>
And this is my pop up in the vIew Model
private async void MakeWebViewLargeEN()
{
var popup = new WordAndPhrasePopup(htmlSourceName.Html);
await PopupNavigation.Instance.PushAsync(popup);
}
I have tried in back of the content page
makeLargerEN.SetBinding(Label.TextProperty, "MakeLargerEN");
Just to swap labels but then the right command doesnt get fired
I have tried this, but gesture doesnt have Command or CommandProperty
makeLargerCZ.SetBinding(GestureRecognizer.Command, new Binding("MakeLargerEN"));
I am doing it in the back of COntent page because i am setting up there another swap that goes along with this one.

You could remove and add GestureRecognize in code behind .
Remove
makeLargerEN.GestureRecognizers.Clear();
Add
makeLargerEN.GestureRecognizers.Add(new TapGestureRecognizer
{
NumberOfTapsRequired = 1,
Command = new Command(() =>
{
//...
}),
});
