How to execute click() in jQuery

This code basically takes 'textmoney' and figures out how much a person makes a year. to execute this function you have to press enter. I also have a div called 'moneydiv' that will do the same function, but it seems if i have both functions in the same script neither will work. How would i code to have the user to be able to do both functions? How would i code the click() with the div?

Jquery:

<script src="http://ift.tt/1yCEpkO"></script>
    <script>
    $(document).ready(function() {

    var $demo = $('#demo');
    var $textMoney = $('#textmoney');
    var $moneydiv = $('#moneydiv');

    .keydown(function(e) {
        if (e.keyCode === 13) {
            var money = $(this).val();
            if (isNaN(money) || money === '') {
                $demo.text('You aint enter no $$$$$$');
            } else {
                var dailyE = $(this).val() / 365;
                $demo.text('$' + dailyE + ' per day');
            }
        } else if ($(this).val() === '') {
            $demo.text('');
        }
    }).mouseover(function() {
        $(this).css('border', '1px solid black');
    }).mouseout(function() {
        $(this).css('border', '1px solid grey');
    });

});
    </script>
