Thanks Derick, this solution is fine for my needs. 

I think you should modify the *reInitializeRegions* as well passing the view options. I think something like that should be ok.

```javascript
  reInitializeRegions: function(){
    if (this.regionManagers && _.size(this.regionManagers)===0){
      this.initializeRegions(this.options);
    } else {
      // ...
    }
  },
```
