react Unexpected token "/"

Hello i am trying to render a component dynamically look:

render: function() {
    return (
        <form  {...this.props}>
            <div className={'row'}>
                {this.props.fields.map(function(field, index){
                    if (index != 0 &&index%3==0) {
                        return (
                            </div><div className={'row'}>
                            <div className={'col-sm-4'}>
                                <div className={'row'}>
                                    <div className={'col-sm-3'}>
                                        <Label htmlFor={'filters_'+field.name}>{field.label}</Label>
                                    </div>
                                    <div className={'col-sm-9'}>
                                        <InputText name={field.name} id={'filters_'+field.name} />
                                    </div>
                                </div>
                            </div>
                        )
                    } else{
                        return (
                            <div className={'col-sm-4'}>
                                <div className={'row'}>
                                    <div className={'col-sm-3'}>
                                        <Label htmlFor={'filters_'+field.name}>{field.label}</Label>
                                    </div>
                                    <div className={'col-sm-9'}>
                                        <InputText name={field.name} id={'filters_'+field.name} />
                                    </div>
                                </div>
                            </div>
                        )
                    }
                })}
            </div>
        </form>
    );
}

but i am getting this error "Parse Error: Line 17: Unexpected token / while parsing file..."

the line 17 in my file is </div><div className={'row'}>

There is another way to do this? and is it possible to put all my duplicated code inside a variable?

Obs: i am using browserify(7.0.x) and reactfy(0.17.1)
