AngularJS Form Validation - Forcing Validation on Submit

An example of how to force AngularJS to validate after submitting... or at least look like it!

HTML

<link rel="stylesheet" href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css">
<form name="myForm" ng-submit="count = count + 1" ng-init="count=0" ng-app>
 <div class="control-group" ng-class="{error: myForm.mobile.$invalid}">
        <label class="control-label" for="mobile">Mobile</label>
        <div class="controls">
            <input type="text" name="mobile" placeholder="07XXXXXXXXX" ng-model="mobile" ng-minlength="11" pattern="[0-9]{3}" required />
            <span ng-show="myForm.mobile.$error.required" class="help-inline">Required</span>
            <span ng-show="myForm.mobile.$error.minlength" class="help-inline">Mobile number should be minimum 11 character starting from 07</span>           
        </div>
    </div>
     
     <div class="control-group">
        <div class="controls">                       
            <input  class="btn" type="submit" value ="submit" />
        </div>
     
         count: {{count}}<br />

<tt>myForm.$invalid = {{myForm.$invalid}}</tt><br/>
    </div>
</form>
