Ajax + browser backbutton = checkbox not working

I have a checkbox which works as it should when I click the normal menu buttons on my webpage to get to the content. But when I go to another page and use the back button to get back to the page which has the checkboxes, the checkboxes stop working.

html:

<div id="filters">
    <ul id="filters-background">
        <li id="option-type">Filter Options</li>
        <li class="wave2"><label for="white">White<input type="checkbox" name="white" value=".White" id="white"></label></li>
        <li class="wave2"><label for="blue">Blue<input type="checkbox" name="blue" value=".Blue" id="blue"></label></li>
    </ul>
</div>

<script type="text/javascript">
    OnSort();
</script>

js:

function OnSort(e) {
    console.log('aaa');

    // filter button click
    var filterCheckboxes = $('#filters input');
    var filters = [];
    filterCheckboxes.change(function() {
        console.log('clicked checkbox');
    });
}

If you look at the above code, the console will output 'aaa' when I click on the back button but if I test a checkbox it will not output 'clicked checkbox' in the console. How can I make it so the checkboxes will keep working even after I use the browser back button?
