    Hello, I'm trying to bind an array of primitive objects to an un-ordered list using the example from the getting started documentation here:

    I'd like to add a button along side each list item that, when clicked, removes the item from the list.

    When I run the example above without the addition of a click event handler, everything works fine as the below link shows:

    However, when I add a click event handler to the same span, or even a neighboring span element as below...

    I get the following error in Chrome's console:

    Uncaught TypeError: Object Coffee has no method 'get'

    and the rest of the list fails to render correctly. Is this a bug or am I binding in an unusual way?

    Thanks in advance, Sam.

    I've realised that I'm actually binding the click event to a non-existent function i.e. 'viewModel.products.handleClick, where 'products' is the source of the template, in actual fact I need to target 'viewModel.handleClick'.

    So I'll change my question, is there anyway to point to an event handler that exists outside of the 'source' binding such as:

        <span data-bind="text: this, click: viewModel.handleClick"></span>

    The scenario which you are trying to implement is not supported. The reason is that Kendo MVVM does not wrap the primitive values into Observable object. Primitive objects does not have a parent method (Observable Object has) and as a result the click binding cannot be resolved.

    In case you would like to bind the click event, please consider source binding the UI to array with objects.
