<a href> not hitting get method in Spring boot

HTML

<div ng-model="currentUser" id="userContainer">{{currentUser.email}}
    <div class="dropdown-content">
        <a href="/logout">Logout</a>
    </div>
</div>

Controller

@RequestMapping(value = "/logout", method = RequestMethod.GET)
public void logout(HttpServletResponse response, HttpServletRequest request) throws Exception {
    Cookie[] cookies = request.getCookies();
    if (cookies != null) {
        for (Cookie cookie : cookies) {
            cookie.setValue("");
            cookie.setMaxAge(0);
            response.addCookie(cookie);
        }
    }

    response.sendRedirect("/index.html");

}

I am running a Spring boot application and have defined the logout controller as a GET method.
When clicking the Logout Div, the url changes to http://******.ngrok.io/logout
but it never hits the Controller method, but when I reload the browser with http://******.ngrok.io/logout URL then the controller gets hit and logs me out of application.
