Как отправить событие в google analytics через js?

function createFunctionWithTimeout(callback, opt_timeout) {
  var called = false;
  function fn() {
    if (!called) {
      called = true;
      callback();
    }
  }
  setTimeout(fn, opt_timeout || 1000);
  return fn;
};
		
 $(".lets_work_form").submit(function() {
			 ga('send', 'event', 'form', 'submit', {
    hitCallback: createFunctionWithTimeout(function() {
      form.submit();
    })
  })});

var form = $(".lets_work_form");
form.submit(function(e) {
    e.preventDefault();
    ga('send', 'event', 'form', 'submit', {
        hitCallback: function() {
            form.submit();
        }
    });
});
