Update export file title and message (PDF, Print)

ashfaq-ahmed

I need to update export file name and message from an input text field, if i try that in button action then download does not works, if i update that inside button extend options then it only gets the title when it was first loaded no dynamic title.

please suggest.

example

title: $("#export_heading").val()

also if i try that in action then download does not work

action: function ( e, dt, node, config ) {
                    this.title = $("#export_heading").val()
                }
