title: Set value of textbox using JQuery
body: <p>My Jade template - </p>
  
  <pre><code>input#main_search.span2(
      style = 'height: 26px; width: 800px;' ,
      type = 'text',
      readonly='true',
      name='searchBar',
      value='test'
  )
  </code></pre>
  
  <p>JS file - </p>
  
  <pre><code>$('#searchBar').val('hi')
  console.log('sup')
  </code></pre>
  
  <p>Console output - </p>
  
  <pre><code>sup
  </code></pre>
  
  <p>But <code>searchBar</code> value stats at test. What am I doing wrong?</p>
