title: Submit input field with button
body: <p>Here I have an input field and button:</p>
  
  <pre><code>&lt;input id="pac-input" class="controls" type="text" placeholder="Search! e.g. Pizza, Pharmacy, Post office"&gt;
  
  &lt;button id="new" class="btn btn-success"&gt;Submit&lt;/button&gt;
  </code></pre>
  
  <p>Now when I type something into input fields and press "enter" I submit input fields</p>
  
  <p>How to make this append when I click on button? So when I click on button to submit input fields?</p>
  
  <p><strong>UPDATE: I just want when I click on btton to simulate submit on input field</strong></p>
