Unable to change user's password

I have an MVC 5 Identity 2 app. I'm trying to change a user's password as follows:

    public async Task<string> ChangePassword()
    {
        var user = await this.UserManager.FindByIdAsync(18);
        PasswordHasher hasher = new PasswordHasher();

        user.PasswordHash = hasher.HashPassword("NewPassword");
        this.UserManager.Update(user);

        return string.Empty;
    }

this.UserManager is defined as:

HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();

The method executes successfully, but the password is not getting changed. Am I missing a step?

I believe UserManager has this handy method:

public virtual Task<IdentityResult> ChangePasswordAsync(
    TKey userId,
    string currentPassword,
    string newPassword
)

EDIT:

This seems to be working for me. A UserManager property is defined as such:

public ApplicationUserManager UserManager
    {
        get
        {
            return _userManager ?? HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
        }
        private set
        {
            _userManager = value;
        }
    }

Then, the password reset method:

//
    // POST: /Account/ResetPassword
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> ResetPassword(ResetPasswordViewModel model)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }
        var user = await UserManager.FindByNameAsync(model.Email);
        if (user == null)
        {
            // Don't reveal that the user does not exist
            return RedirectToAction("ResetPasswordConfirmation", "Account");
        }
        var result = await UserManager.ResetPasswordAsync(user.Id, model.Code, model.Password);
        if (result.Succeeded)
        {
            return RedirectToAction("ResetPasswordConfirmation", "Account");
        }
        AddErrors(result);
        return View();
    }

UserManager has these methods to change user's passwords:

public virtual Task<IdentityResult> ResetPasswordAsync(TKey userId, string token, string newPassword)

public virtual Task<IdentityResult> ChangePasswordAsync(TKey userId, string currentPassword, string newPassword);

protected virtual Task<IdentityResult> UpdatePassword(IUserPasswordStore<TUser, TKey> passwordStore, TUser user, string newPassword);
