How to get kendo grid data-item on row button click?

I'm using Kendo jQuery UI and trying to get data item on button click where button is on each rows.

function onMybuttonClick(id) {
    row = $(this).closest("tr");
    grid = $("#OrgUserGridAD").data("kendoGrid");
    dataItem = grid.dataItem(row);
}

in data binding:

{
    field: "Action",
    template: function (dataItem) {
        return "<button type='button' class='btn btn - primary' onclick=\"onMybuttonClick('" + dataItem.id + "')\">My Button</button>";
    },
    width: 150
}
