How to Create and Use Enum in Mongoose

I am trying to create and use an enum type in Mongoose. I checked it out, but I'm not getting the proper result. I'm using enum in my mongoose schema as follows:

var RequirementSchema = new mongoose.Schema({ 
status: { 
type: String, 
enum : ['NEW', 'STATUS'], 
default: 'NEW' 
}, 
})

But I am a little bit confused here, how can I put the value of an enum like in Java NEW("new"). How can I save an enum into the database according to its enumerable values? I am using it in express node.js.
