Send form on external page inAppBrowser

Is it possible to send form automatic on external page like in my android ionic application. I just trying ionic-cordova-inappbrowser-plugin and executeScript? but its not working
public subscribe() {

        let browser = null;

        browser = this.inAppBrowser.create('', '_blank');

            () => {
                                  .innerText='12345677' document.getElementById('send').click()"});
         err => {
                console.log("InAppBrowser loadstart Event Error: " + err);

P.S. I know that id button wrong
