title: KnockoutJS how to bind textarea value property to function
body: <p>I have simple <code>textarea</code> that i want to customize it's text(like add break-lines), that's what I have tried so far:  </p>
  
  <pre><code>&lt;textarea rows="5" data-bind="value: function(data) { SetDefaultValue(data); }" /&gt;
  </code></pre>
  
  <p>but I get nothing. </p>
  
  <p>When checking the resulting HTML it doesn't find the value property and has no JavaScript errors. How can I bind <code>value</code> property of a <code>textarea</code> to function.</p>
