Badge is not visible when i add a renderer to navigate to root page on tab reselected

[kamranmasud]

I want to show badge on cart tab..on the other side i want to show root page on tab clicked or reselected..I am using your plugin to show badge on tab but when i use renderer to show root page on tab reselected then badge is not visible. I am finding the solution because i want both of these functionalities in my app..
I am using the following renderer to navigate to root page when i reselect tab:

[assembly: ExportRenderer(typeof(TabPage), typeof(MainPageRenderer))]
namespace MyProject.Droid.Renderers
{
public class MainPageRenderer : TabbedPageRenderer, TabLayout.IOnTabSelectedListener
{
private TabPage _page;
protected override void OnElementChanged(ElementChangedEventArgs e)
{
base.OnElementChanged(e);
if (e.NewElement != null)
{
_page = (TabPage)e.NewElement;
}
else
{
_page = (TabPage)e.OldElement;
}

    }
    async void TabLayout.IOnTabSelectedListener.OnTabReselected(TabLayout.Tab tab)
    {
        await _page.CurrentPage.Navigation.PopToRootAsync();
    }
}

}
