addeventlistener function not working as expected

I am not able to see the data in firebase database after giving the input through UI. Can anyone please help.

   <body>
      <input id="username" type="text" placeholder="Name"><br/>
      <input id="text" type="text" placeholder="Message"><br/>
      <button id="post">Send</button><br/>
      <div id="results"></div>
      <script>
        var myFirebase = new Firebase('http://ift.tt/2v80BH5');
        var usernameInput = document.getElementByID("username");
        var textInput = document.getElementByID("text");
        var postButton = document.getElementByID("post");

        postButton.addEventListener("click", function() {
          myFirebase.push(usernameInput + " says: " + textInput);
          textInput.value = "";
        },false);
