I met following error in the console when using **angular-bootstrap ui**. I have angular 1.2.6, bootstrap 3.0, and angular-bootstrap 0.10.0.

**Error: [$compile:ctreq] Controller 'accordion', required by directive 'accordionGroup', can't be found!**

Anyone know why it happens?
My html code.

```
<div ui-view>
        <accordion-group id="crud-talbe" ng-repeat="grid in grids" heading="{{grid.name}}">
            <a ng-click="createNewEntity(grid.name)" class="btn btn-default">create new {{grid.name}}</a>
            <div class="crudGridStyle" ng-grid="grid" />
        </accordion-group>

```
