Changing the Spring Security Core and Groovy Grails login form

Good afternoon, I made a change in my application to use my login form instead of the standard Spring Security Core, the redirection is occurring normally, however when clicking the button to enter nothing happens. Here is the code for my form:

<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?
