How to add button to a view dynamically in android xamarin?

I am trying to add a button dynamically to a View in a droid app using xamarin.android. I need to be able to do this as i will have to add few things dynamically during the project. Heres the code i am trying out. 

public class FeedbackFragment : Android.Support.V4.App.Fragment
{
    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        var view = inflater.Inflate (Resource.Layout.ChallengeFeedbackView, container, false);

        LinearLayout parentLayoutView = view.FindViewById (Resource.Id.feedbackView);//LinearLayout
        ScrollView feedbackscrollView = parentLayoutView.FindViewById (Resource.Id.scrollView1);//ScrolView

        var scrollviewInnerContainerView = feedbackscrollView.FindViewById (Resource.Id.scrollViewInnerContainer);
        scrollviewInnerContainerView.SetBackgroundColor (Android.Graphics.Color.White);//Linear Layout

        var silhouteeContainer = scrollviewInnerContainerView.FindViewById (Resource.Id.view1);//View

        Button b1 = new Button (this);
        b1.SetText ("Click Me");

        LinearLayout.LayoutParams prm = new LinearLayout.LayoutParams (LinearLayout.LayoutParams.MatchParent,LinearLayout.LayoutParams.MatchParent);

     // I want to achieve something like this
       silhouteeContainer.AddView(b1); //when i actually do this , it shows an error.

        return view;
    }
}

And here's what the fChallengeFeedbackView.axml looks ike. 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/feedbackView"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/scrollView1">
        <LinearLayout
            android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/scrollViewInnerContainer">
            <View
                android:layout_width="fill_parent"
                android:layout_height="275dp"
                android:id="@+id/view1"
                android:background="#00ff00" />
            <View
                android:layout_width="fill_parent"
                android:layout_height="275dp"
                android:id="@+id/view2"
                android:background="#ff0000" />
            <View
                android:layout_width="fill_parent"
                android:layout_height="275dp"
                android:id="@+id/view3"
                android:background="#0000ff" />
        </LinearLayout>
    </ScrollView>
</LinearLayout>

The problem is that you cannot add child views to something which inherits from View. In order to do this the type must inherit from ViewGroup. Such layouts are LinearLayout, FrameLayout and RelativeLayout.

So adding elements to your three declared View instances in your AXML file, is not possible.
