              style=&quot;visibility: {{ btn_Guardar }} ;&quot;&gt;Guardar&lt;/button&gt;

  <p>Just made a new test and this has definitely something to do with de quotation marks. I can see in the console window that <code>&quot;visibility: '{{ btn_Guardar }}'</code> leave the quitación marks &quot;on&quot; <code>style=&quot;visibility:'hidden';&quot;</code> and that's why it is not working. The question still remains what to do?</p>
