What is the issue with this getJSON request

Honestly for the life of me can't figure out what is wrong with this code and why I am getting an error. I defined the url, data, and the callback function and simply call getJSON with the params, still get a Bummer so can someone explain what I am doing wrong please

weather.js
$(document).ready(function() {

  var weatherAPI = 'http://api.openweathermap.org/data/2.5/weather';
  var data = {
    q : "Portland,OR",
    units : "metric"
  };
  function showWeather(weatherReport) {
    $('#temperature').text(weatherReport.main.temp);
  }

  $.getJSON(weatherAPI, data, showWeather())
});
index.html
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>What's the Weather Like?</title>
  <script src="jquery.js"></script>
  <script src="weather.js"></script>
</head>
<body>
  <div id="main">
    <h1>Current temperature: <span id="temperature"></span>&deg;</h1>
  </div>
</body>
</html>

What you need to do is pass the reference to the function, but not call it:

$.getJSON(weatherAPI, data, showWeather) // no parens ()

The 3rd argument here needs to be a function, which will jQuery will call later, we're not calling it yet. It's the function that will be called when the response comes back.
