javascript - React bootstrap Navbar: How to right align a navbar item

Question

I'm trying to right align a navbar item (Contribute) within a navbar.js but I can't seem to figure it out. The navbar is a React component and looks like the following,

navbar.js here

import React, {PropTypes} from 'react';
import { Link, IndexLink } from 'react-router';
import { browserHistory, Router, Route } from 'react-router'
var ReactDOM = require('react-dom');

// create classes
var NavBar = React.createClass({
  render: function(){
    return(
      <nav className="navbar navbar-inverse navbar-static-top">
        <div className="container-fluid">
          <div className="navbar-header">
            <button type="button" className="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse" aria-expanded="false">
              <span className="sr-only">Toggle navigation</span>
              <span className="icon-bar"></span>
              <span className="icon-bar"></span>
              <span className="icon-bar"></span>
            </button>
            <NavBrand linkTo={this.props.brand.linkTo} text={this.props.brand.text} />
          </div>
          <div className="collapse navbar-collapse" id="navbar-collapse">
            <NavMenu links={this.props.links} />
          </div>
        </div>
      </nav>
    );
  }
});

var NavBrand = React.createClass({
  render: function(){
    return (
      <Link to={ this.props.linkTo }>
        <span className="navbar-brand">{this.props.text}</span>
      </Link>
    );
  }
});

var NavMenu = React.createClass({
  render: function(){
    var links = this.props.links.map(function(link){
      if(link.dropdown) {
        return (
          <NavLinkDropdown key={link.text} links={link.links} text={link.text} active={link.active} />
        );
      }
      else {
        return (
          <NavLink key={link.text} linkTo={link.linkTo} text={link.text} active={link.active} />
        );
      }
    });
    return (
      <ul className="nav navbar-nav">
        {links}
      </ul>
    );
  }
});

var NavLinkDropdown = React.createClass({
  render: function(){
    var active = false;
    var links = this.props.links.map(function(link){
      if(link.active){
        active = true;
      }
      return (

        <NavLink key={link.text} linkTo={link.linkTo} text={link.text} active={link.active} />

      );
    });
    return (
      <ul className="nav navbar-nav navbar-right">
      <li className={"dropdown" + (active ? "active" : "")}>
        <a href="#" className="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">
          {this.props.text}
          <span className="caret"></span>
        </a>
        <ul className="dropdown-menu">
          {links}
        </ul>
      </li>
      </ul>

    );
  }
});

var NavLink = React.createClass({
  render: function(){
    return(
      <li className={(this.props.active ? "active" : "")}>
        {/*<a href={this.props.linkTo}>{this.props.text}</a>*/}
        <Link to={ this.props.linkTo }>
          <span className="NavLink">{this.props.text}</span>
        </Link>
      </li>
    );
  }
});

module.exports = NavBar;

Presently, my navbar looks like the following,

The best and easiest approach which works is to add following class to the NAV node like following:

<Nav className="ml-auto">

Unfortunately adding "pullRight" wasn't the solution and it won't work.
