How to call add method

[RupenAnjaria]

The source file (https://github.com/McNull/angular-form-gen/blob/master/src/angular-form-gen/angular-form-gen.js)
has a reference to add function at line 55. Do anyone know how to call this function while using the the generated form?

    .config(['fgConfigProvider', 'FgField', function (fgConfigProvider, FgField) {

        var field = new FgField('Component', {
            displayName: 'component',
            value: void 0
        });
        fgConfigProvider.fields.add(
            field,
            'Components',
            require('./field.html'),
            require('./field-config.html')
        );
    }])
