Angular ng-repeat to access object with in an object

Framework: AngularJS 1.4.X
Problem: Accessing Object with in Object
In Built directive: ng-repeat

In Directive:

for ( i=0; i< something.lenght < i++)
    if ( element in elements ){
        sendData[i]=
        {
           pair:element,
           row:i
        } 
    } 
}
scope.obj[sendData] = sendData;

In View:

<somedirective obj="obj">
    <md-content ng-repeat="data in obj">
         {{obj[data].pair}}  or {{data.pair}}
    </md-content>
</somedirective>

Console Log ( JSON.stringify(scope.obj) ):

{"[object Object]":{"14":{"pair":"HIT|CEDR3","row":14},"15":{"pair":"HIT|CEPR3","row":15},"16":{"pair":"HIT|CEKR3","row":16},"24":{"pair":"Book|Pro0","row":24}}

{{data}}:

{"14":{"pair":"HIT|CEDR3","row":14},"15":{"pair":"HIT|CEPR3","row":15},"16":{"pair":"HIT|CEKR3","row":16},"24":{"pair":"Book|Pro0","row":24}}

I'm not able to access pair property from the second object in ng-repeat, as i mentioned in the view section i have used {{obj[data].pair}} or {{data.pair}} and if i use {{data}} it will print all object property/data list.

scope.obj = {};
for ( i=0; i< something.lenght < i++)
    if ( element in elements ){
        sendData[i]=
        {
           pair:element,
           row:i
        } 
    } 
}
scope.obj = sendData;

I hope this will help others, and thank you Oskar.
