ckeditor update textarea from javascript

I have used CKEditor a year now and everything has worked as it should.
Now I need to change the text in the textarea using javascript.
I have created an example that illustrates my problem.

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>CKEditor Sample</title>
    <script type="text/javascript" src="/ckeditor/ckeditor.js"></script>
    <script type="text/javascript">
      function othertext() {
        document.getElementById('button').value = 'xxx';
        document.getElementById('noteditor').innerHTML = '<h1>Hello other world!</h1><p>I&#39;m also an instance of <a href="http://ckeditor.com">CKEditor</a>.</p>';
        document.getElementById('editor').innerHTML = '<h1>Hello other world!</h1><p>I&#39;m also an instance of <a href="http://ckeditor.com">CKEditor</a>.</p>';
        CKEDITOR.replace('editor');    
      }  
    </script>
  </head>
  <body id="main">
    <input type="button" id="button" onclick="othertext();" value="NewText" />
    <br>
    <textarea id=noteditor>
      <h1>
        Hello world!
      </h1>
      <p>
        I&#39;m an instance of <a href="http://ckeditor.com">CKEditor</a>.
      </p>
    </textarea>
    <br>
    <textarea name=text id=editor>
      <h1>
        Hello world!
      </h1>
      <p>
        I&#39;m an instance of <a href="http://ckeditor.com">CKEditor</a>.
      </p>
    </textarea>
    <script type="text/javascript">   
      CKEDITOR.replace('editor');    
    </script>
  </body>
</html>

When I click the button, the value of the button changes, the same with the first textarea (id=noteditor).
But textarea (id=editor) is not affected.
Why?
In debugger, when the line "CKEDITOR.replace('editor1');" in function othertext is executed I get <exception>:TypeError.
What am I doing wrong?

I found a solution to my problem! By chance I found the answer to my question here: http://sdk.ckeditor.com/samples/api.html under "Using CKEditor API". I have rewritten my first code here below:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>CKEditor Sample</title>
    <script type="text/javascript" src="/ckeditor/ckeditor.js"></script>
    <script type="text/javascript">
      function SetContents() {
        // Get the editor instance that you want to interact with.
        var editor = CKEDITOR.instances.editor_Area1;
        var value = document.getElementById('HTMLArea' ).value;

        // Set editor content (replace current content).
        // http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-setData
        editor.setData( value );
      }
    </script>
  </head>
  <body id="main">
    <input type="button" id="button" onclick="SetContents();" value="Set text" />
    <br>
    <textarea id=HTMLArea>
      <h1>
        Hello other world!
      </h1>
      <p>
        I&#39;m an other instance of <a href="http://ckeditor.com">CKEditor</a>.
      </p>
    </textarea>
    <br>
    <textarea name=text id=editor_Area1>
      <h1>
        Hello world!
      </h1>
      <p>
        I&#39;m an instance of <a href="http://ckeditor.com">CKEditor</a>.
      </p>
    </textarea>
    <script type="text/javascript">   
      CKEDITOR.replace('editor_Area1');    
    </script>
  </body>
</html>

When clicking on the button, the content of the editor-area is replaced by the html from the textarea "HTMLArea".
