To send data from C# page to HTML we need to call javascript function defined in that HTML file. We are having Eval function in Xamarin Forms.

WebViewObj.Eval(string.Format("JSFunctionName({0})", DataInStringFormat));

By using above function we can send the data to JavaScript function.

You probably want to look at the documentation for creating a HybridWebView.

This document describes how you can create your own kind of WebView which can handle JavaScript events for you. Although it may not be 100% accurate to what you want, it will give you an idea and you can pick it up from there.

As you noted in the comment you need to implement C# to JS. In the same custom renderers you can call functions for this on the WebViews. For iOS you can use InvokeJavaScript(); and for Android (mis)use LoadUrl("javascript: alert('Hi!');").

For more info on this, follow this great post by Adam Pedley.
