$("#grid").kendoGrid({

    autoBind: false,
    editable: true,
    filterable: true,
    toolbar: ["save", "cancel"]
});

sharedDataSource.read();

The answer by @Edin is correct; it works. But the cause wasn't quite clear. Short investigation leads to a quite simple fix; simply remove the tabindex from the modal, like so:

<!-- not working with tabindex -->
<div id="myModal1" class="modal hide" tabindex="-1" role="dialog">

<!-- this will -->
<div id="myModal1" class="modal hide" role="dialog">

That also fixes your original fiddle.
