Adding ID and Class on template dynamically using backbone views

I want to add a ID and CLASS attribute to my view template.
this is what i tried but failed.

$("#login").html( _.template( LoginTemplate ) );
         this.loginmodel = new LoginModel();
         this.loginview = new LoginView({
             el: $("#loginContainer"),
             model: this.loginmodel,
             className: "test"
         });
 
 <div id="loginContainer">
     <div id="loginForm">
       <input class="user-input formContainerInput" id="username" placeholder="Username" required="required"/>
       <input class="user-input formContainerInput"  id="password" type="password" placeholder="Password" required="required"/>
       <a class="connection-btn" data-role="button">Connection</a>
       <a class="login-btn" data-role="button">Log In</a>
     </div>
 

I want to assign id and class using the views and not on the html itself. How will i do it?
