Problems with Kendo UI Grid Editing

Question

I tried use the Kendo Grid and i found some problems.

The button action "edit" and "remove " do nothing when i click, but if i put the "create" command into the transport, the grid send lots of POSTS for the create URL command when i click in delete or click in edit > cancel (the update button do nothing too).

What I doing wrong?

My code:

<div id="grid"></div>
<script type="text/x-kendo-template" id="template">
    <div class="toolbar">      
    <input type="number" min="0" id="item-id" maxlength="10"  />
    <input type="text" id="name" class="k-textbox" placeholder="..." />
    <button style="width: 100px" id="btn-grid-filtrar" class="k-button" >Filter</button>
</div>
</script>

<script>
    $(document).ready(function() {

        var dataSource = new kendo.data.DataSource(
        {
            schema: 
            {
                data: "data",
                total: "total",
                model: 
                {
                    id: "data",
                    fields: 
                    {
                        id: { editable: false, nullable: false },
                        nome: { type: "string", validation: { required: true} },
                        ativo: { type: "boolean" }
                    }
                }
            },                  
            transport: 
            {
                read: 
                {
                    url: "page",
                    dataType: "json",
                    type: "POST",
                    data: additionalData
                },
                update: {
                    url: "update",
                    dataType: "jsonp"
                },
                destroy: {
                    url: "delete",
                    dataType: "jsonp"
                }
                /*,
                create: {
                    url: "add",
                    dataType: "jsonp"                   
                }
                */
            },
            pageSize: 5,
            serverSorting: true,
            serverPaging: true,
        });

        var grid = $("#grid").kendoGrid({
            dataSource: dataSource,
            sortable: true,
            pageable: {
                input: true,
                numeric: false
            },
            batch: true,
            columns: [
                { field: "id", title: "#", width: "60px" }, 
                { field: "nome", title: "Nome" }, 
                { field: "ativo", title: "Ativo", width: "60px", template: "#= ativo ? 'Sim' : 'Não' #" },
                { command: ["edit", "destroy"], title: "Ações", width: "200px" }
            ],
            editable: "inline",
            toolbar: kendo.template($("#template").html()),             
        });

        kendo.bind($(".toolbar"));

        $("#id").kendoNumericTextBox({
            format: "##########",
            placeholder: "..."
        });

        $("#btn-grid-filtrar").click(function() {
            grid.data("kendoGrid").dataSource.read();
        });
    });

    function additionalData() {
        return {
            filtro_id: $("#item-id").val(),
            filtro_nome: $("#name").val()
        };
    }

First of all, I'm assuming that you server is serving a JSON with the following format:

{
    "total": 2,
    "data" : [
        {
            "data" : 23,
            "id"   : 1,
            "ativo": true,
            "nome" : "stock-1"
        },
        {
            "data" : 34,
            "id"   : 2,
            "ativo": false,
            "nome" : "stock-2"
        }
    ]
}

Correct?

So the first thing is changing the "data" on each row data to something not called data. It turns out that data is a kind-of reserved word in KendoUI commonly used in code structures as:

with (data) {
    // Expanded code coming from a grid row data
}

Where this data is a variable referencing a row in your grid. So, in this context data is both the row itself and and a field in that row and then JavaScript cannot correctly solve it.

So you can define your schema as:

schema       : {
    data : "data",
    total: "total",
    model: {
        id    : "_data",
        fields: {
            id   : { editable: false, nullable: false },
            nome : { type: "string", validation: { required: true} },
            ativo: { type: "boolean" }
        }
    }
},

NOTE: I've replace data by _data.

Transmitted data is:

{
    "total": 2,
    "data" : [
        {
            "_data" : 23,
            "id"   : 1,
            "ativo": true,
            "nome" : "stock-1"
        },
        {
            "_data" : 34,
            "id"   : 2,
            "ativo": false,
            "nome" : "stock-2"
        }
    ]
}

Just with this small change your Edit button will start working.

You are not supposed to define transport level for local datasources, if understand correctly your code, you are not posting anywhere - you are not binding any remote data, I can't see any url ? Follow this example http://demos.kendoui.com/web/datasource/index.html.
