Fired when the value of the widget is changed by the user.

The event handler function context (available via the this keyword) will be set to the widget instance.

Example - subscribe to the "open" event after initialization

<div id="signature"></div>
<script>
    function signature_open() {
        console.log("open");
    };
    $("#signature").kendoSignature();
    var signature = $("#signature").data("kendoSignature");
    signature.bind("open", signature_open);;
</script>
