如何从kendo UI中的dataSource获取某些字段值

Question

I have defined dataSource like this:

var dataSource = new kendo.data.DataSource({
  data: [
    {Id: 1, name: "Jane Doe", description: "some description", numberValue: "3000.00" },
    {Id: 2, name: "John Connor", description: "description temp", numberValue: "1800.00" },
    {Id: 3, name: "T-100", description: "descr tmp", numberValue: "2200.00"}
  ],
  schema: {
        model: {
            id: "Id",
            fields: {
                Id: { type: "number" },
                name: { type: "string" },
                description: { type: "string" },
                numberValue: { type: "number" }
            }
        }
    }
});

How can I get certain field value from dataSource? For example: I want get value for field numberValue (where Id = 1, or Id = 2 or Id = 3). If I call dataSource.data.numberValue then nothing happening. Any help really appreciated. Thank you in advance.

dataSource.data显然是一个数组。
