Calling Vaadin JS function from cordova.InAppBrowser

General

we have defined the following JS function in Vaadin
JavaScript js = com.vaadin.ui.JavaScript.getCurrent();

js.addFunction(‘js_image_succeded’, new JavaScriptFunction() {

        @Override
        public void call(final JsonArray arguments) {

            UI.getCurrent().access(new Runnable() {
                
                @Override
                public void run() {
                    
                    succeeded(arguments);
                }
            });

        }

    });

We are running an hybrid mobile app, In UIwebview within iOS, we are able to call these using stringByEvaluatingJavaScriptFromString.

Now porting into Android and using cordova here.
i used var ref = cordova.InAppBrowser.open(url, target, options);

Here, now am unable to call these javascript functions from cordova.

Tried the following

  1. js_image_succeded(); //directly
  2. ref.executeScript({ code: “js_image_succeded()”});

it says I/chromium: [INFO:CONSOLE(314)]
“Uncaught ReferenceError: js_image_succeded is not defined”

kindly let me know anyway we can call these JS functions please
