Use Mvvmcross Binding with MonoTouch.Dialog (Lists and Commands) - binding

Question

1. Binding Lists
I wonder how I could bind a ObservableCollection to a Radiogroup:
new Section(){
new RootElement("Mandanten", new RadioGroup("mandanten", 2)) {
new Section(){
new RadioElement("Kupus", "mandanten"),
new RadioElement("Kajmak", "mandanten")
}
}
}
as you see here I'm creating 2 Items/Elements manually but I miss something like an "ItemsSource".
If its not possible, what recommendation would you give me? To use witch Control (to bind Lists)?
2. CommandBinding
As I see theres no "button" in MonoTouch.Dialog. So I saw that we'll use "StringElement".
I tried it, but after tapping on the "button" nothing happened:
new StringElement("Login").Bind(this, "SelectedCommand LoginCommand")
I'm not sure whats wrong, maybe I need to use here the new "variant", like that:
new EntryElement ("User", "Loginuser", ViewModel.User).Bind(target, v => v.Value, t => t.User),
But I'm not sure how to build that similiar code to bind a command for a particular "stringelement" (in that case - a button with the ontap event)..
Any help appreciated!

1. Binding lists
An example of binding dynamic ObservableCollection lists is in https://github.com/slodge/MvvmCross-Tutorials/blob/master/DialogExamples/DialogExamples.Touch/Views/ThirdView.cs - it uses some custom elements from https://github.com/slodge/MvvmCross-Tutorials/tree/master/DialogExamples/DialogExamples.Touch/BindableElements - which was based on the sample from https://github.com/asednev/MvvmCross.AlexeysExtensions
Because of the way Radio lists are internally implemented, I don't know if the same ObservableCollection binding approach would work for radio lists - someone would need to prototype and experiment to work this out. However, a simple fixed radio list is shown in https://github.com/slodge/MvvmCross-Tutorials/blob/master/DialogExamples/DialogExamples.Touch/Views/FirstView.cs
2. CommandBinding
See an example in: https://github.com/slodge/MvvmCross-Tutorials/blob/master/DialogExamples/DialogExamples.Touch/Views/FirstView.cs
new Section("Action")
{
new StringElement("Second").Bind(bindings, element => element.SelectedCommand, vm => vm.GoSecondCommand),
new StringElement("Bindable Elements").Bind(bindings, element => element.SelectedCommand, vm => vm.BindableElementsCommand)
},
