title: Update div after form submit
body: <p>my first post on Stackoverflow.</p>
  
  <p>I'm building a page with bootstrap and php. 
  I have a value load from a database in a text field in a div.</p>
  
  <p>In the same page I have a button loading a modal where I have a form with the same value load in a text field. </p>
  
  <p>So if the user changes the value in the form and hits update I would like the modal to close and the value update on the page.</p>
  
  <p>All the modal, form, load and save database is working. The place where I'm stuck is the div refresh data part. </p>
  
  <p>Any advice. </p>
