I am trying to convert a JQuery website to AngularJS, but I can't figure this one out.  

**In JQuery I used:**

```
$('.bet').change(function(e)  {
    // Do someting
};

```

I tried to do multiple things with AngularJS but no success.  

At the moment I have this in my HTML and I have nothing related in my Angular file

**index.php**

```
<input type="number" class="form-control" id="bet" name="bet" placeholder="Your bet" ng-model="bet" ng-change="bet( {{bet}} )"/>

```

How to do this in AngularJS?
