progress bar not binding a values in angularjs

Question

Hi,

 

This is my progress bar code :

 

<div class="form-group col-md-8 center " ng-init="Communication=0" data-ng-model="Candidate.Communication">
<label for="input-Default" class="col-sm-3 control-label" style="padding-top:20px" ng-class="submitted?'ng-dirty':''" required autofocus><b>Communication Skills</b></label>
<span class="col-sm-9">
<input type="text" name="com" id="addcandidaterange_communication">

</span>

</div>

 

When I select the value but it was not binded.

 

 

 

Please give me a correct code for that.

 

Thank you.
