How to store user defined schema and save data based on that schema

Working with Data
5

This is the code to save userDefinedSchema in the database, idea is that later i can read it back from tableSetup collection and use it to save new data for the user defined collection.

			var userDefinedSchema = {
				  title: String,
				  body: String,
				  date: 
					{
					  type: String,
					  default: Date.now()
					}
				  }; 

			var tableUploadSetup = {
			  setupId:String,
			  userDefinedSchemaDetails:Object
			  };

			const tableSetupSchema = new Schema(tableUploadSetup);
			const newTableSetupModel = moogoose.model('TableSetup',tableSetupSchema);


			const newTableSetupData = {
			  setupId: 'SETUP001',
			  userDefinedSchemaDetails:userDefinedSchema
			};

			const newTableSetup = new newTableSetupModel(newTableSetupData);

			newTableSetupModel.save((error) =>{
			if(error){
				console.log('error: '+error)
			  } else{
				console.log('data is saved !!!')
			   }
			 })

still new to mongodb, not sure whether this is the right approach. thanks for your reply.
