Question

<div class="form-group fields col-xs-12 col-sm-6 col-md-4 col-lg-4" ng-class="{'has-error' : (submitted || tForm.password.$dirty || tForm.submitted) && tForm.password.$invalid }">
    <input type="password" name="password" placeholder ="Password*" class="form-control1" autocomplete="off"  ng-model="model.password" ng-minlength="8" ng-maxlength="20" required ng-pattern="/(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#$^*)(._-])(?=.*[^a-zA-Z._-])(?=.*[^a-zA-Z._-])/"  />
<div ng-show="!tForm.password.$error.required && (tForm.password.$error.minlength || tForm.password.$error.maxlength) && tForm.password.$dirty" class="help-block">Passwords must be between 8 and 20 characters.</div>
       <div ng-show="!tForm.password.$error.required && !tForm.password.$error.minlength && !tForm.password.$error.maxlength && tForm.password.$error.pattern && tForm.password.$dirty" class="help-block">Must contain one lower &amp; uppercase letter, number and one non-alpha character (except %,",")</div>
      <div ng-show="(submitted && tForm.password.$error.required) " class="help-block">password is required.</div>
       </div>
