title: Adding a Dynamic Child to my Firebase Reference URL
body: <p>I've been attempting to dynamically add a child to my firebase data reference URL, so far with no luck.</p>
  
  <p>Assume I have the following data structure:</p>
  
  <p>MyApp<br>
  |-beta_signups<br>
  |-users<br>
  |--fred<br>
  |----email "fred@test.com"</p>
  
  <p>I would like to be able to add people who sign up, as a child based on their email address under the "signups" section. here is what I tried, but it didn't work.</p>
  
  <pre><code>var myDataRef = new Firebase("https://myapp.firebaseio.com/beta_signups/");
    $('#submit').click(function() {
        var email = $('#email').val();
        myDataRef.child(email).push({email: email, beta_key: false});
        $('#email').val('We got it.');
    });
  </code></pre>
  
  <p>Any suggestions on how I can dynamically add the child? </p>
