Add new data to typeahead result on scroll

Question

I'm using angular bootstrap typeahead. I would like to add a functionality for infinite scroll in that, for that i have added a small directive for scroll functionality and some changes in typeahead template, scroll directive works as expected but typeahead not updating a view after result is update.

My input is like :

<input type="text" ng-model="variable" placeholder="Search..." typeahead="obj as obj.text for obj in getObject($viewValue)" typeahead-wait-ms="500" />

typeahead template :

<ul class="dropdown-menu typeahead-custom" ng-scroll="getObject('{{query}}')" ng-scroll-direction="down" ng-show="isOpen()" ng-style="{top: position.top+'px', left: position.left+'px'}" style="display: block;" role="listbox" aria-hidden="{{!isOpen()}}">
    <li ng-repeat="match in matches track by $index" ng-class="{active: isActive($index) }" ng-mouseenter="selectActive($index)" ng-click="selectMatch($index)" role="option" id="{{match.id}}" should-focus="isActive($index)">
        <div typeahead-match index="$index" match="match" query="query" template-url="templateUrl"></div>
    </li>
</ul>

and getObject Function :

$rootScope.lastResult = [];
$rootScope.getObject = function(str) {
    return  $http({
        url: "someUrl",
        method: "post",
        headers: {'Content-Type': 'application/json'},
        data: {str: str, page_limit: 10}
    }).then(function(response) {
        $.merge($rootScope.lastResult, response.data.data);
        return $rootScope.lastResult;
    });
};

when I type something in typeahead input it works fine, but when i scroll into the typeahead template it calls a function and updating lastResult variable but didn't updating a DOM element of typeahead.

Any help? Please....

Please try this one !!

$rootScope.lastResult = [];
$rootScope.getObject = function(str) {
    return  $http({
        url: "someUrl",
        method: "post",
        headers: {'Content-Type': 'application/json'},
        data: {str: str, page_limit: 10}
    }).then(function(response) {
        $rootScope.$apply(function(){
         $.merge($rootScope.lastResult, response.data.data);
        });
        return $rootScope.lastResult;
    });
};
