Lag scrolling TableView Xamarin.Forms

I have a little problem... In xamarin.forms I created a TableView and I added different custom cells.

The problem is that I have lag when scrolling the table and some cells disappear. In iOS I was able to fix the problem with a renderer with this:
UITableViewCell cell = tv.DequeueReusableCell("Xamarin.ViewCell");
but I don´t know how to fix it in Android.

Can somebody help me?
Thanks
