Android Custom Switch Render disable Switch.Toggled event

I created a switch with a label related to it, in the sense that when Switch in turned on/off the label change it's text. Then I created a custom switch render who work very well for me, but I have an inconvenience: with the render my switch continue to work, but label not change.
I attach the code below.

Switch Toggle Event:

private void OnSwitchToggled(object sender, EventArgs e) {
            if (swcSave.IsToggled) {
                lblSave.Text = "text1";
            } else {
                lblSave.Text = "text2";
            }
        }

Switch Custom Render:

using Xamarin.Forms.Platform.Android;
using Android.Widget;
using Android.Graphics;
using MyApp.Droid;

[assembly: Xamarin.Forms.ExportRenderer(typeof(Xamarin.Forms.Switch), typeof(SwitchRenderer_Android))]
namespace MyApp.Droid
{
    class SwitchRenderer_Android : SwitchRenderer
    {

        private Color blue = new Color(56, 103, 150);
        private Color yellow = new Color(243, 146, 0);

        protected override void Dispose(bool disposing)
        {
            Control.CheckedChange += this.OnCheckedChange;
            base.Dispose(disposing);
        }

        protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.Switch> e)
        {
            base.OnElementChanged(e);

            if (this.Control != null) {

                if (this.Control.Checked) {
                    this.Control.ThumbDrawable.SetColorFilter(yellow, PorterDuff.Mode.SrcAtop);
                    this.Control.TrackDrawable.SetColorFilter(yellow, PorterDuff.Mode.SrcAtop);

                } else {
                    this.Control.ThumbDrawable.SetColorFilter(blue, PorterDuff.Mode.SrcAtop);
                    this.Control.TrackDrawable.SetColorFilter(blue, PorterDuff.Mode.SrcAtop);
                }

                this.Control.CheckedChange += this.OnCheckedChange;
            }
        }

        private void OnCheckedChange(object sender, CompoundButton.CheckedChangeEventArgs e)
        {
            if (this.Control.Checked)
            {
                this.Control.ThumbDrawable.SetColorFilter(yellow, PorterDuff.Mode.SrcAtop);
                this.Control.TrackDrawable.SetColorFilter(yellow, PorterDuff.Mode.SrcAtop);
            }
            else
            {
                this.Control.ThumbDrawable.SetColorFilter(blue, PorterDuff.Mode.SrcAtop);
                this.Control.TrackDrawable.SetColorFilter(blue, PorterDuff.Mode.SrcAtop);
            }
        }

    }
}
