GroupBy filter is not working in angularJs

I have created a table in angularjs. Now I am trying to group the table rows based on a column value whose title is "source".

For that, I am using groupBy filter. It is not giving any error. But it is displaying empty rows now. Can someone tell me where I am going wrong?

Below is my code:

 <table>
    <thead>
        <tr>
           <th>Metric</th>
           <th>Source</th>
           <th class="value">Value</th>
           <th></th>
        </tr>
        </thead>
        <tr ng-repeat="metric in metrics | filter:query | orderBy:orderProp | groupBy:'info.source'>
            <td class="metric">{{metric.name}}</td>
            <td class="source">{{metric.info.source}}</td>
            <td class="value">{{metric.info.value}}</td>
       </tr>
    </table>

I am pasting a sample of my Json data to get you an idea about my table data:

[{
  "name": "kafka.health",
  "info": {
    "source": "kafka",
    "value": "OK",
    "timestamp": "1459438855068",
    "causes": ""
  }
},
{
  "name": "kafka.bringo.health",
  "info": {
    "source": "kafka",
    "value": "Error",
    "timestamp": "1459438855068",
    "causes": ""
  }
}]

I myself found the solution of my problem. Correct way to use "groupBy" filter in table is as below:

var app = angular.module("myApp", ['angular.filter']);
app.controller("SimpleController", function($scope) {
  $scope.metrics =  [{
  "name": "kafka.health",
  "info": {
    "source": "kafka",
    "value": "OK",
    "timestamp": "1459438855068",
    "causes": ""
  }
},
{
  "name": "kafka.bringo.health",
  "info": {
    "source": "kafka",
    "value": "Error",
    "timestamp": "1459438855068",
    "causes": ""
  }
},
{
  "name": "dm.bingo.health",
  "info": {
	"source": "deployment-manager",
	"value": "Error",
	"timestamp": "1459438855068",
	"causes": ""
  }
},
{
  "name": "dm.different.health",
  "info": {
	"source": "deployment-manager",
	"value": "Warn",
	"timestamp": "84834883483",
	"causes": ""
  }
},
{
  "name": "kadmfka.bringo.health",
  "info": {
	"source": "deployment-manager",
	"value": "Error",
	"timestamp": "1459438855068",
	"causes": ""
}
}];
});

Use 

 <tr ng-repeat="(key, value) in metrics | groupBy:'info.source' ">

DEMO

var app = angular.module("myApp", ['angular.filter']);
app.controller("SimpleController", function($scope) {
  $scope.metrics =  [{
  "name": "kafka.health",
  "info": {
    "source": "kafka",
    "value": "OK",
    "timestamp": "1459438855068",
    "causes": ""
  }
},
{
  "name": "kafka.bringo.health",
  "info": {
    "source": "kafka",
    "value": "Error",
    "timestamp": "1459438855068",
    "causes": ""
  }
}];
});
