Android : Webview autofill not working for password in android

I am trying to auto fill the webview in android but it is not working properly. I am trying to fill both username and password but it is just populating username not password. I am using below code for this.

view.evaluateJavascript("javascript:document.getElementById('username').value = '"+username+"';javascript:document.getElementById('password').value = '"+password+"';",null);

Any suggestion. I am using API level 19.
