title: Getting a value from a label at POST
body: <p>There's a place into my screen that I populate a label with a specific string value after some interaction with my user during the runtime. I use javascript for that.</p>
  
  <p>Is there anyway to get the value of this lavel with my controller after its <code>POST</code> method is activated ?</p>
  
  <p>Thanks, guys ! </p>
