How htmlUnit works with data-ember-action?

I have a input

<input value="http://change" id="view_data_edit" maxlength="2048" data-bindattr-29="29" class="ie6bug" type="text">   

and a button

<button class="atp_button pull-right marginright_17p fontweight_thick" id="submit" data-ember-action="24"><span id="i18n-8">Save</span></button>

I use

   final WebClient webClient = new WebClient(BrowserVersion.FIREFOX_52);
    webClient.getBrowserVersion().setOnLine(true);
    webClient.getBrowserVersion().setBrowserLanguage("ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3");
    webClient.setJavaScriptTimeout(20000);
    webClient.getOptions().setTimeout(20000);
    webClient.waitForBackgroundJavaScript(20000);
    webClient.setRefreshHandler(new ImmediateRefreshHandler());
    webClient.setAjaxController(new NicelyResynchronizingAjaxController());
    webClient.getOptions().setGeolocationEnabled(true);
    webClient.getOptions().setRedirectEnabled(true);
    webClient.getOptions().setUseInsecureSSL(true);
    webClient.getOptions().setCssEnabled(true);
    webClient.getOptions().setActiveXNative(true);
    webClient.getOptions().setAppletEnabled(true);
    webClient.getOptions().setJavaScriptEnabled(true);
    webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
    webClient.getOptions().setThrowExceptionOnScriptError(false);

    webClient.addRequestHeader("Upgrade-Insecure-Requests", "1");
    webClient.addRequestHeader("DNT", "1");

and then after go to the site

  final HtmlTextInput url = (HtmlTextInput) advancetr069.getElementById("view_data_edit");
    url.setText("http://123453qw");


  final HtmlButton  save_submit = (HtmlButton) advancetr.getElementById("submit");
    final HtmlPage save_submitPage = save_submit.click();

The value in input does't change. I think that this is because button use

data-ember-action
