How to repeatedly call a function from application.js?

Question

Ruby on Rails

Good afternoon.
I do the example #240 Search, Sort, Paginate with AJAX - RailsCasts
In order to implement live seach, the following is done there.

#application.js
$(function() {
  $("#contracts_search input").keyup(function() {
    $.get($("#contracts_search").attr("action"), $("#contracts_search").serialize(), null, "script");
    return false;
  });
});

But this function works only the first time when loading. How to implement so that it always works?

Answer 1

$(document).on('keyup', '#contracts_search', function() {
  // event handler
});
