Changing the Spring Security Core and Groovy Grails login form

Question

Good afternoon, I made a change in my application to use my login form instead of the standard Spring Security Core, the redirect is occurring normally, however when clicking the Login button nothing occurs. Follow the code of my form below:

<from action='${request.contextPath}/j_spring_security_check' method="POST" name="logar" id="logar" class="form-horizontal">
        <div class="control-group">
            <label class="control-label" for="username">Email</label>
            <div class="controls">
                <input type="text"  placeholder="Email" name="j_username" id="username">
            </div>
        </div>
        <div class="control-group">
            <label class="control-label" for="password">Senha</label>
            <div class="controls">
                <input type="password"  placeholder="Senha" name="j_password" id="password">
            </div>
        </div>
        <div class="control-group">
            <div class="controls">
                <label class="checkbox">
                    <input type="checkbox"> Lembre-se de mim
                </label>
                <input type="submit" class="btn" value="Entrar" />
            </div>
        </div>
    </from>

Any suggestions ?
