Unsolved Call a C++ function from HTML in QWebEngineView, Is it Possible ?

[Discode]

Hello There
I have a QWebEngineView to load a Web Page from local content.
In that HTML page there is a Script include a variable "myVar", now i can get value of myVar but button click in C++,
but my question is this:
Is there any way to call a function in C++ whenever "myVar" changed ?
something like this:

<script>
        var myVar = null;
        function initVar(){
               myVar = 'sample string';
               // now call function ( funcInCpp(myVar);)
        }
</script>

Is there any way to do this ? if yes please help me
Tnx
