input type = submit does not work in internet explorer

Hello,

I have a form that makes a POST call with a <input type="submit"> to make the call to the server. The fact is that I work correctly in Firefox and Chrome, but not in IE.

I have been observing in several threads that to make it work you have to add a name , but even then I can not get the call made.

Has this happened to anyone? I leave the code:

<form action="{{url('simulador/result')}}" method="POST">

        <div class="col-md-12 setup-content text-center cajas-inicio" id="step-1">
            <button id="activate-step-2" class="action-button shadow animate blue">Siguiente</button>
        </div>
    </div>
</div>
<div class="row">
    <div class="col-xs-12">
        <div class="col-md-12 setup-content text-center cajas-inicio" id="step-2">
            <h1 class="text-center"> Fecha de nacimiento del conyuge</h1></br>
            <h2>&larr; Seleccione una de las dos opciones &rarr;</h2>
                <div class="row">
                    <div class="col-md-6">
                        <img src="/img/icons/holding-hands.png" alt="">
                        <input type="radio" name="calculo" value="si" id="radio1" class="radio">
                        <label for="radio1" style="background-color: gainsboro">Calculo con conyuge</label> 
                    </div>

                    <div class="col-md-6">
                        <img src="/img/icons/school-teacher.png" alt="">
                        <input type="radio" name="calculo" value="no" id="radio2" class="radio">
                        <label for="radio2" style="background-color: gainsboro">Calculo sin conyuge</label>

                    </div>
                </div>

            <div id="calendar">
                <p>Introduzca la fecha de nacimiento del conyuge</p><br>
                <input type="text" name="fechaConyuge" id="datepicker"></br>
            </div>
            <input type="submit" class="action-button shadow animate blue" name="validar">
            </div>
        </div>

</form>
