ng-click不触发功能

Question

<button ng-click="overlayShow('#overlay-exceptions')"
        class="ds-button ds-primary">
    <div class="ds-align-text-center">SUBMIT NEW REQUEST</div>
</button>

// To open overlays and correctly handles the background page
$rootScope.overlayShow = function(id) {
    id = $(id);
    console.log(id)
    var list = $rootScope.openOverlays;

    if(list.length == 0) $('#gsi-html').addClass('gsi-no-scroll');
    if(list.indexOf(id) < 0) {
        list.push(id);
        id.addClass('ds-open');
    }
}

ng-click按钮未触发该功能。关于如何解决此问题的任何想法，我认为这可能是语法错误。
