KeyPress on input not worked

Question

I need create keyPress (enter) binding for input.

<div id="body">
    <input type="text" data-value-update="keyup" data-bind="value: text, keyPress: onKeyPress"/>
    <div id="output"></div>
</div>

js:

kendo.data.binders.widget.keyPress = kendo.data.Binder.extend({
    init: function (element, bindings, options) {
        kendo.data.Binder.fn.init.call(this, element, bindings, options);
        var binding = this.bindings.keyPress;
        $(element.input).bind("keypress", function (e) {
            if (e.which == 13) {
                binding.get();
            }
        });
    },
    refresh: function () { }
});

var viewModel = kendo.observable({
    text: '',
    onKeyPress: function () {
        $("#output").append("<div>keyPress</div>");
    }
});

kendo.bind("#body", viewModel);

I had have error:

Error: The keyPress binding is not supported by the input element

The kendo.data.binders.widget namespace should be used when creating widget bindings. Widgets are created for elements that have their role data attribute set. You need kendo.data.binders only:

kendo.data.binders.keyPress = kendo.data.Binder.extend({
});

More info is available in the custom binding help topic.
