Error appears when using 'minMode' together with 'maxDate' or 'minDate'

This screenshot shows the error on the console after I clicked the datepicker http://i.imgur.com/RnxTQmG.png

Error: [$compile:nonassign] Expression '{'minMode': 'month', 'maxDate': filters.month_to}' used with directive 'uibDatepickerPopup' is non-assignable!

Basically, I'm trying to create a "Month Range Picker" for my app so I used the combination of minMode and minDate/maxDate

here's the sample html markup:


<!-- Month From -->
<input type="text"
class="form-control" 
datepicker-options="{'minMode': 'month', 'maxDate': filters.month_to}"
ng-model="filters.month_from"
uib-datepicker-popup="MMM-yyyy"
show-button-bar="false"
readonly
is-open="monthFromDP"
placeholder="MM-YYYY"/>

<!-- Month To-->
<input type="text"
class="form-control" 
datepicker-options="{'minMode': 'month', 'maxDate': filters.month_from}"
ng-model="filters.month_to"
uib-datepicker-popup="MMM-yyyy"
show-button-bar="false"
readonly
is-open="monthToDP"
placeholder="MM-YYYY"/>

Here's a plunk to reproduce what I'm saying: http://plnkr.co/edit/cXEWPIknF4SjNzdbEJUY?p=preview

If I remove the minMode option, the error goes away.
