title: how to generate form and text from string using knockoutjs?
body: <p>I have a string like this :</p>
  
  <p><code>var par = 'hello my name is @firstname.'
  </code></p>
  
  <p>with knockout js i want to generate this string to a form and text, may be like this :</p>
  
  <pre><code>&lt;input type="text" data-bind="value:firstname" /&gt;
  
  &lt;p&gt;
  hello my name is &lt;span data-bind="text:firstname"&gt;&lt;/span&gt;.
  &lt;/p&gt;
  </code></pre>
  
  <p>so <code>@firstname</code> will generate an input with value firstname, and every update on firstname will update the paragraph.</p>
  
  <p>i create a jsfiddle to testing :
