body: <p>I have a simple question about angularjs one-way-data-binding. </p>
  
  <p>Assume that in same page, we have two input box <strong>A</strong> and <strong>B</strong>, </p>
  
  <p>How can they work like: </p>
  
  <p>input <strong>A</strong> will change input <strong>B</strong>, but input <strong>B</strong> will NOT change input <strong>A</strong>,</p>
  
  <p>I know angular has bindonce, but I want is one-way-data-binding </p>
