How can I check dynamic checkboxes with jquery

I am trying to find the easiest way to check change event checkboxes.

I created checkboxes with php script

PHP:

<div class="form-group">
    <div class="col-md-12 servicesCheck" style="margin-top:-10px">
        <?php
        foreach ($data["languageSchool"]["services"] as $service) {
            $required = "";
            $checked = "";
            if ($service["is_required"] == "1") {
                $required = "disabled";
                $checked = "checked";
            }
            echo "<div class='checkbox " . $required . "'>";
            echo "  <label><input id='services' type='checkbox' " . $checked . " " . $required . " value='" . $service["price"] . "'>" . $service["name"] . "</label>";
            echo "</div>";
        }
        ?> 
    </div> 
</div>

JQUERY:

$('#servicesCheck :checkbox').change(function () {
    // DO SOMETHING
});

What did I do wrong in my code.
