Angular JS Action on ng-change the select dropdown

Question

I have a simple table with three rows and two values for each row - date and state:

<tbody>
   <tr>
      <td>Red</td>
        <td class="lastModified">{{item.redDate}}</td>
        <td class="status"> 
            <select id ="red" class="form-control" ng-change="update();" ng-model="item.redStatus">
              <option value="" disabled="" selected="" class="ng-binding">Please select the value</option>
              <option ng-selected="step.value === item.redStatus"  ng-repeat="(key, step) in steps">{{ step.title }}</option>
            </select>
       </td>
   </tr>
   <tr>Green</tr>
   <tr>
     ....
   </tr>                    
</tbody>

So, simple date and status values for red, green and blue. One in dropdown - status, the second - just output date.

On change the select value - i need to update the date with today's date.

 `$scope.item.redDate = new Date();`

Is it possible to have one function like ng-change="change();" Can't send with ng-change the ID...

Special thanks to Samir Das with help to find the solution ng-change="update(id);":

<select id ="red" class="form-control" ng-change="update(id);" ng-model="item.redStatus">
          <option value="" disabled="" selected="" class="ng-binding">Please select the value</option>
          <option ng-selected="step.value === item.redStatus"  ng-repeat="(key, step) in steps">{{ step.title }}</option>
 </select>

Here is the controller:

$scope.update = function(id){
    id = event.target.id;
    $scope.item[id+'Date'] = new Date();
 };
