IE 11 input not displaying typed text

A work's client has reported an issue in our application when working with IE11.

On an specific form, sometimes, when opening it, if you type, the typed text won't show. If I open developer tools, it suddenly shows.

This is the rendered html belonging to that form:

<div class="col-sm-6 ">
<div class="form-group" data-ng-show="myform.txtPropietario.visible">
<label class="col-md-4 control-label my-show-hide-animation">Propietario:</label>
<div class="col-md-8"> 
<div class=" ">
<input name="txtPropietario" class="form-control text-left ng-pristine ng-valid" input-alpha-numeric="ES" onblur="this.value=this.value.toUpperCase();" data-ng-model="myform.values.txtPropietario" data-ng-disabled="myform.txtPropietario.disabled" type="text" step="0.01" maxlength="50" placeholder="  "></div> 
<ul class="errores my-show-hide-animation ng-hide" data-ng-show="myform.seccionPanelPagoServiciosname.txtPropietario.$invalid &amp;&amp; myform.procesado"><li data-ng-show="myform.seccionPanelPagoServiciosname.txtPropietario.$error.required" class="ng-hide"><span>Campo obligatorio</span></li><li data-ng-show="myform.seccionPanelPagoServiciosname.txtPropietario.$error.pattern" class="ng-hide"><span>El formato del dato ingresado no es válido.</span></li>
</ul>
</div>
</div>
</div>

The app work's over AngularJs and html is built over Bootstrap 3. Any idea why is this happening?
