Android access MvxDialogFragment view from service - xamarin.android

Question

I am using MVVMCross, and have a problem with MvxDialogFragment bindings.
I have a base service, which is resolved in Core PCL project, add custom services implementations in iOS and Android projects derived from the base service class.
In android service i construct and show MvxDialogFragment instance:
var top = (MvxFragmentActivity)Mvx.Resolve<IMvxAndroidCurrentTopActivity>().Activity;
if (top == null)
{
throw new MvxException("Cannot get current top activity");
}
var dlg = new AlertDialog.Builder(top);
dlg.Create().Show();
dialog = new MyDialog
{
Cancelable = false
};
dialog.Show(top.SupportFragmentManager, "");
And i have simple dialog layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/test_click_button"
android:text="Test"
app:MvxBind="Click TestClickCommand" />
</LinearLayout>
So my goal is to acces base service commands from dialogFragment, which is instantiated from service. How can i do that?
As an alternative, i want to handle my button click in service, but cannot find a way to do this, because my View, ViewModel or Dialog properties are null.
How it's possible to handle clicks in service, or implement self binding?

Finally i achieved the desired, through MvxDialogFragment subscription, and service injection:
public class MyDialog : MvxDialogFragment
{
private ISampleService _sampleService;
public MyDialog(ISampleService sampleService)
{
_sampleService = sampleService;
}
public override Dialog OnCreateDialog(Bundle savedInstanceState)
{
EnsureBindingContextSet(savedInstanceState);
var dialog = new AlertDialog.Builder(Activity);
var view = this.BindingInflate(Resource.Layout.MyDialog, null);
view.FindViewById(Resource.Id.test_click_button).Click += (sender, e) =>
{
_sampleService.TestClick();
Dismiss();
};
dialog.SetView(view);
return dialog.Create();
}
}
