Kendo Unbind ViewModel and rebind to other

Question

I have viewmodel that i use for 'add' form. On that form i have 1 textbox called 'description'. First time user enter some text in that field. Whan user press cancel( on the same form ) and then press Add again the form appearing with entered value in the 'description' field.

I want to create new view model and unbind all model with wrong value. But when i do that:

kendo.unbind($("#notes-dialog"));
kendo.bind($("#notes-dialog"), notesWindowModel);

the old value persist in the description textbox.

EDIT:

notesWindowModel = kendo.observable(
        {
            text: '2'
        });

    kendo.bind($("#notes-dialog"), notesWindowModel);

    var notesWindowModel2 = kendo.observable(
        {
            text: '4'
        });

    kendo.unbind($("#notes-dialog"));
    kendo.bind($("#notes-dialog"), notesWindowModel2);

Why does my field equal 2?

If i add

notesWindowModel.set('text', 'aaaa');

at the end my value equals 'aaaa'. It means that element is binded to first model. What is wrong here?

I found the problem:

 <div id="notes-dialog">
    <div id="notes-dialog-window" data-role="window" data-width="410" data-height="510"   data-actions="" data-modal="true" data-title="false" style="display: none;">
    <div id="notes-new-item">
        <div>
            <h3>Notes</h3>
            <div>
                <span>Note</span> <span>Is Delay?</span><span><input data-bind="value: model.Entity.IsDelay" class='k-input notes-checkbox' type='checkbox' /></span>
            </div>
            <div>
                <textarea class="k-input utility-analysis-textarea notes-textarea" data-bind="value: text"></textarea>

The problem was that i have kendo window inside that element and when i open that window first time it replaces HTML and binding was wrong.

Old thread but I've recently faced the same issue. In my case I've just had to destroy all kendo elements:

kendo.destroy(document.body);
