title: JComponent global method GET doesn't work in Total.js Flow components
body: <p>I have a problem in Total.js Flow using inside a component the client-side method GET to retrieve value of JComponent ( in my case textbox or input ).
  I have tried from Componentator and actually works, but inside my Total.js Flow ( version 6, but the 5 version has the same problem ) it return undefined. Someone know any solution or better way to retrieve for example on button click the value inside the input box?</p>
  
  <pre><code>&lt;div class="row"&gt;
      &lt;div class="col-md-12"&gt;
          &lt;div data-jc="textbox" data-jc-path="url"&gt;@(URL)&lt;/div&gt;
       &lt;/div&gt;
   &lt;/div&gt;
   &lt;button onclick="getUrl()"&gt;Try&lt;/button&gt;     // this call an example function that call the "console.log"
  
  
  console.log(GET('url'));    // return undefined
  </code></pre>
