angularjs - Combining data in firebase -

hello i'm trying combine data retrieved 3 different locations in firebase. data structured follows:

dashboard.data.post       dashboard.data.post.image      dashboard.data.post.audio      dashboard.data.post.text 

when user posts able make post underneath 1 of blocks. able search underneath block of users posts , retrieve information, combine all, ordered data post , display user. far method feel rudimentary , appreciate advice possible, if means restructuring data.

info.block = $firebasearray of id's users have of post info.text $firebasearray of texts post info.image $firebasearray of image post info.audio $firebasearray of audio post  var storage = function(text, image, audio, value, liststore) {                 var postkey = value.postid;                 angular.foreach(info.text, function(curr, key) {                     if (postkey === curr.$id) {                         liststore.push(curr);                         return true;                     }                 });                 angular.foreach(info.image, function(curr, key) {                     if (postkey === curr.$id) {                         liststore.push(curr);                         return true;                     }                 });                 angular.foreach(info.audio, function(curr, key) {                     if (postkey === curr.$id) {                         liststore.push(curr);                         return true;                     }                 });             };  info.blog.$loaded().then(function() {             info.text.$loaded().then(function() {                 info.image.$loaded().then(function() {                     info.audio.$loaded().then(function() {                         angular.foreach(info.blog, function(value, key) {                             storage(info.text,info.image,info.audio,value,this);                         }, $scope.randomobj);                      });                 });             });         });
