Application made with Xamarin does not execute JavaScript

I've developed a small application with WebView in Xamarin, it loads the page correctly, but is not running JavaScript, JavaScript with webView.Settings.JavaScriptEnabled = true; but no success, I have no experience with Xamarin , do I need to do anything else?

  

MainActivity.cs

[Activity(MainLauncher = true, Theme = "@android:style/Theme.NoTitleBar.Fullscreen")]
    public class MainActivity : Activity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);

            var webView = FindViewById<WebView>(Resource.Id.webView);

            // Use subclassed WebViewClient to intercept hybrid native calls
            webView.SetWebViewClient(new HybridWebViewClient());
            webView.Settings.JavaScriptCanOpenWindowsAutomatically = true;
            webView.Settings.JavaScriptEnabled = true;
            webView.LoadUrl("http://financas.gopagoda.io");


        }

        private class HybridWebViewClient : WebViewClient
        {
            public override bool ShouldOverrideUrlLoading(WebView webView, string url)
            {

                // If the URL is not our own custom scheme, just let the webView load the URL as usual
                var scheme = "hybrid:";

                if (!url.StartsWith(scheme))
                    return false;

                // This handler will treat everything between the protocol and "?"
                // as the method name.  The querystring has all of the parameters.
                var resources = url.Substring(scheme.Length).Split('?');
                var method = resources[0];
                var parameters = System.Web.HttpUtility.ParseQueryString(resources[1]);

                return true;
            }
        }
    }

  

Main.axml

<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/webView" >
</WebView>

I get this error in the console:
