title: __doPostBack seems not working in an external JS file
body: <p>As the title mention I have a separated JS file that interarcts with my ASP.Net page. At the begining, all the JS function were inside the ASP.Net page including the __doPostBack method and all was working OK. But, once I moved the JS functions to a separated file to keep up my page clear all the functions were working as normal except the one that use the __doPostBack.</p>
  
  <p>Now I can't call my C# function from codebihind 'cause the __doPostBack is not executed.</p>
  
  <p>So, Does anyone of you know if this method works in a separeated JS file? If so, waht would be the correct code to execute it? Or Do I need to maintain it in the same file where my ASP.Net code is?</p>
  
  <p>Thanks for your help in advance
  Regards!</p>
