Hi,

I found that the range is not showing properly at startup / page load if I set the max value as binding from ng-model instead of number

work fine:

```
<input type="range" name="loadperyear_range" min="{{setup.loadperyear_min}}" max="500000" step="{{setup.loadperyear_step}}" ng-model="data.loadperyear" >

```

not working:

```
<input type="range" name="loadperyear_range" min="{{setup.loadperyear_min}}" max="{{setup.loadperyear_max}}" step="{{setup.loadperyear_step}}" ng-model="data.loadperyear" >

```

Here’s a playground trying to explain the problem I’m facing : [http://play.ionic.io/app/2f0bc4a5215f](http://play.ionic.io/app/2f0bc4a5215f)  
use the + or - on the bottom range to see the problem clearly

any advice?
