Phonegap Java call Javascript Function

Question

I am currently making a hello world type Phonegap application for android, In which I call a javascript function from the native android code to set the text of one of the paragraphs in my app.

I have a javascript function that I define in my app's html, and I want to call it from my activity once the app loads up. The function just sets the text of a paragraph in my app. I cannot get this to work.

Here is my java activity code:

public class MyPhoneGapActivity extends DroidGap {

    public DroidGap c;
    public LoadInfo info;

    @SuppressLint("SetJavaScriptEnabled") 
    @JavascriptInterface
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.init();
        c = this;
        appView.getSettings().setJavaScriptEnabled(true);
        appView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        appView.loadUrl("file:///android_asset/www/index.html");

        appView.setWebViewClient(new WebViewClient() {
            public void onPageFinished(WebView view, String url) {
                MyPhoneGapActivity.this.runOnUiThread(new Runnable() {
                    public void run() {
                        c.sendJavascript("javascript:getMassTimes()");
                    }
                });
            }
        });
    }
}

and here is my javascript and html code:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport"
    content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

    <script type="text/javascript">
        function getMassTimes() {
            document.getElementById("massTimes").textContent = "This is some text";
        }
    </script>
    <div>
        <header-bar title="Saint David the King"
            class="bar bar-header bar-energized">
        <h1 class="title">Saint David the King</h1>
        </header-bar>
        <br>
        <content scroll="true" has-header="true" width="100%" height="100%"
            id="content"> <img alt="Saint David the King"
            src="file:///android_asset/www/img/saintdavidthekingbackground2.png"
            width="100%" /> <br>
        <p id="massTimes">
        </p>
        </content>
    </div>
</body>
</html>

Is there something I am doing wrong? I have seen these sites:
