[SOLVED] dropdown with add new item in a grid column

dropdown with add new item in a grid column

I've already implemented a dropdown in a grid column according to this demo: https://demos.telerik.com/kendo-ui/grid/editing-custom

I already did a test with this custom dropdown: https://demos.telerik.com/kendo-ui/dropdownlist/addnewitem

I am wondering if it's possible to add this custom dropdown in a column of the grid to add a new category if the category is not found in the dropdown.

The column doesn't show in the column Comment.

I tried the following code without success, some tips of how to solve this?

EDIT 1: I tried the abinesh solution, and I think it is very close to solving this issue(http://dojo.telerik.com/OZIXOlUM). Still, the addNew function expects the widgetID. In the onclick of the add new button, the widgetID is passing nothing (see print screen). How did I get this ID? The script "noDataTemplate" is trying to get the id this way '#:instance.element[0].id#', but as I said, nothing returns.

<script id="noDataTemplate" type="text/x-kendo-tmpl">
        <div>
            No data found. Do you want to add new item - '#: instance.filterInput.val() #' ?
        </div>
        <br/>
        <button class="k-button" onclick="addNew('#: instance.element[0].id #', '#: instance.filterInput.val() #')">Add new item</button>
    </script>
    
 <script>
        $(document).ready(function(){
            var dataSource = new kendo.data.DataSource({
                data: categories
            });

            var gridDataSource = new kendo.data.DataSource({
                data : [ {
                    "Commen": "-",
                    "Confirmed": 1,
                    "Stat": 1
                },
                {
                    "Commen": "-",
                    "Confirmed": 1,
                    "Stat": 1
                },
                {
                    "Commen": "-",
                    "Confirmed": 1,
                    "Stat": 1
                },
                {
                    "Commen": "Some Comment",
                    "Confirmed": 1,
                    "Stat": 1
                }]
            });

            $("#grid").kendoGrid({
                dataSource: gridDataSource,
                height: 550,
