IE 11 input not displaying typed text : <p>A work's client has reported an issue in our application when working with IE11.</p>

<p>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.</p>

<p>This is the rendered html belonging to that form:</p>

<pre><code>&lt;div class="col-sm-6 "&gt;
&lt;div class="form-group" data-ng-show="myform.txtPropietario.visible"&gt;
&lt;label class="col-md-4 control-label my-show-hide-animation"&gt;Propietario:&lt;/label&gt;
&lt;div class="col-md-8"&gt; 
&lt;div class=" "&gt;
&lt;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="  "&gt;&lt;/div&gt; 
&lt;ul class="errores my-show-hide-animation ng-hide" data-ng-show="myform.seccionPanelPagoServiciosname.txtPropietario.$invalid &amp;amp;&amp;amp; myform.procesado"&gt;&lt;li data-ng-show="myform.seccionPanelPagoServiciosname.txtPropietario.$error.required" class="ng-hide"&gt;&lt;span&gt;Campo obligatorio&lt;/span&gt;&lt;/li&gt;&lt;li data-ng-show="myform.seccionPanelPagoServiciosname.txtPropietario.$error.pattern" class="ng-hide"&gt;&lt;span&gt;El formato del dato ingresado no es válido.&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
</code></pre>

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