Q:

I'm facing another problem with Angular Material. 
Now I have a form, with two select.  The problem is when I select one value in any of this two select, the other one get reseted and loose his value. 
is this a bug?  or maybe I'm doing something wrong? 
<form name="addTarjeta">
  <div ng-controller="MedioPagoController">
      <md-input-container class="md-icon md-block">
          <label>Tipo de tarjeta</label>
          <md-icon class="material-icons">&#xE252;</md-icon>
          <md-select ng-model="_tarjeta.medioPago" md-on-open="listaMedioPago()"
                     required name="medio">                                            
              <md-option value="{{medio}}" 
                         ng-repeat="medio in medioPagos track by medio.idMedioPago">{{medio.nombrePago}}</md-option>                                            
          </md-select>
      </md-input-container>
  </div>
  <div ng-controller="EntidadBancariaController">
      <md-input-container class="md-icon md-block">
          <label>Entidad bancaria</label>
          <md-icon class="material-icons">&#xE84F;</md-icon>
          <md-select ng-model="_tarjeta.medioPago" md-on-open="listaEntidadBancaria()"
                     required name="entidad">                                            
              <md-option value="{{entidad}}" 
                         ng-repeat="entidad in entidadBancarias">{{entidad.nombreEntidad}}</md-option>                                            
          </md-select>
      </md-input-container>
   </div>  
</form>

A:

As I post in a comment:
You are binding both selects to the same ng-model="_tarjeta.medioPago", so this is the expected behaviour. 
I think it's probably just a typo in your code.  Could you check it? 
Change the ng-model of (probably) your second select to another variable of the controller and the problem should disapear. 
Hope it helps
