ng-模型不工作

<div ng-show="discount.discount.days_details.monday.enable"
     class="add-time-block"
     ng-class="showInterval">
    <button ng-click="discount.addInterval('monday', start_m, end_m);"
            class="edit blue">{{::discount.lc.b_add_period}}
    </button>
    <div class="input-group bootstrap-timepicker">
        <input type="time" placeholder="hrs:mins" ng-model="start_m"
               value="00:00"
               pattern="^([0-1]?[0-9]|2[0-4]):([0-5][0-9])(:[0-5][0-9])?$"
               class="timepicker-rest-from">
        <strong>-</strong>
        <input type="time" placeholder="hrs:mins" ng-model="end_m" value="00:00"
               pattern="^([0-1]?[0-9]|2[0-4]):([0-5][0-9])(:[0-5][0-9])?$"
               class="timepicker-rest-to">
    </div>
    <div>
        <span ng-repeat="interval in discount.discount.days_details.monday.intervals">{{::interval.from}} - {{::interval.to}}<br></span>
    </div>
</div>

底线是我使用angular-bootstrap-datepicker并且只有版本angular 1.3.5兼容它，但因此它不能正常工作ng-model。结果start_m，他们start_end会的undefined。
我无法将日期选择器更改为另一个，因为网站上的所有内容都是基于布局的。
但是如果你把angular放在上面1.3.5，比如 ，1.4.9那么就会出现这样的错误

Controller 'select', required by directive 'ngOptions', can't be found!

<div id="datepicker0" ng-datepicker 
    dp-options="discount.datepickersOptions.from"
    ng-model="discount.discount_dates.from"></div>

如何解决这个问题？

我将附上ng-bootstrap-datepicker的链接
