I have a dictionary:

```
{ "69": true, "72": true, "97": true, "113": false, "136": true, "189": false, "396": true, "404": false, "454": false }

```

How i can filter this data by value using angularjs? I need to get this (Only true):

```
{ "69": true, "72": true, "97": true, "136": true,  "396": true}

```
