Question

i have tried pagination using uib-pagination,everything seems to work fine, but the only thing is that i am not able to attach the page number with active class.

<uib-pagination 
    class="center-child" 
    total-items="filterData.length" 
    ng-model="page"
    ng-change="pageChanged()" 
    previous-text="&lsaquo;&lsaquo;" 
    next-text="&rsaquo;&rsaquo;" 
    items-per-page=3>
</uib-pagination>
