AngularJs ng-click在Bootstrap下拉菜单上不起作用

Question

I am using bootstrap 3 CSS only without bootstrap js or jQuery with AngularJs framework, But I have a very basic usage issue which is ng-click not get fired on bootstrap dropdown

HTML

<div class="fc-couponThumbnail">

<i class="icon-ok" ng-if="coupon.couponMainImage=='couponThmub1'"></i>
<div class="dropdown">
    <button  type="button" class="dropdown-toggle" >
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu"  >
        <li ><a ng-click="coupon.couponMainImage='couponThmub1';">set main image</a></li>
        <li><a ng-click="coupon.couponThmub1=''">delete</a></li>
    </ul>
</div>

as I am not using bootstrap js so I made this directive to get dropdown toggled

angular.module('FansCoupon').directive('dropdownToggle', function () {
return{
    restrict:'C',
    link:function(scope,ele,attrs){

        ele.on('click', function () {
                ele.parent().toggleClass('open')

        })
        ele.on('blur', function () {
            ele.parent().removeClass('open')
        })
    }
}
})

Edit I

When I instantiate .dropdown with open class the ng-click work properly!

Edit II

calling a function instead of do javascript directly in ng-click didn't worked too.

Finally the solution for my issue was to use Angular UI Bootstrap which handling all bootstrap components as angular Js directives so I used uib-dropdown , uib-dropdown-toggle and uib-dropdown-menu

and my code now looks like :

<div class="dropdown" uib-dropdown >
<button  type="button" uib-dropdown-toggle class="dropdown-toggle" >

    <span class="caret"></span>
</button>
<ul class="dropdown-menu" uib-dropdown-menu >
    <li ><a ng-click="coupon.couponMainImage=coupon.couponThmub4;">set main image</a></li>
    <li><a ng-click="coupon.couponThmub4=''">delete</a></li>
</ul>
