title: TextBox's enable disable using knockout observable dynamically?
body: <p>I am trying to run a loop on div having three controls of type text-boxes .</p>
  
  <p>I built a sample fiddle which  explain basic structure <code>:</code> <a href="http://jsfiddle.net/JL26Z/60/" rel="nofollow">http://jsfiddle.net/JL26Z/60/</a></p>
  
  <p>I have to work out something where i have to enable/disable text boxes based on status .</p>
  
  <p><strong>Case 1 :</strong> if i have status value of 1 or 2 entire row should be disabled i.e all 3 text boxes should be disabled</p>
  
  <p><strong>Case 2 :</strong> If i have status value of 3 i need 1st text-box and last text box disabled leaving 2nd text-box  editable</p>
  
  <p><strong>Case 3 :</strong> if it has any other status value other than what i mentioned above i just need to make it editable all of them .</p>
  
  <p>Well i have to make use of some binding attribute to achieve this i tried using </p>
  
  <p><code>attr:{disable:true}</code> or <code>attr:{disable:false}</code> but this wont help me i have to do something unconventional if/else .</p>
  
  <p>Any suggestions are much appreciated </p>
