There are several ways to set the 'choices' property.

// The classic way to set the property. The result values are numbers: 1 and 2
choices: [{ value: 1, text: "Value 1" }, { value: 2, text: "Value 2" }]
// The values are: 1 and 'Value 2' and texts are '1' and 'Value 2'
choices: [{ value: 1 }, { value: "Value 2" }]
// The values and texts are same
choices: ["Value 1", "Value 2"]
// The values are '1' and '2' and texts are 'Value 1' and 'Value 2'
choices: ["1|Value 1", "2|Value 2"]
