Hi there,

how can i get the key of the (key, value) to a button to send it as msg.payload in ng-click?  
In this part i want to insert the {{key}} from the ng-repeat but that doesn't seem to work.

```auto
<md-button ng-click="msg.payload = {{key}}; send(msg);">SAVE</md-button>

```

Complete ui template code:

```auto
<div ng-repeat="(key, value) in msg.payload">
    <div ng-if="value > 0">
        <p ng-style="{'background-color':'green'}">
            {{key}}: {{value}}
        </p>
        <div>
             <md-button ng-click="msg.payload = {{key}}; send(msg);">SAVE</md-button>
        </div>
    </div>
</div>

```

Thanks!
