How to set longitude, latitude with maker in google map?

I Have list populated from sqlite

          <ion-item class="item-remove-animate item-avatar item-icon-right" ng-repeat="category in branChcategories | filter:input.searchInput" type="item-text-wrap" href="#/tab/locations/"   ng-class-odd="'odd'" ng-class-even="'even'"
            <h2>&nbsp; {{category.slno}}.&nbsp;&nbsp;{{category.branch_name}}</h2>     
    		<h2>Ph :&nbsp;{{}}</h2>
    		<h2>Fax :&nbsp;{{category.fax}}</h2>
            <i class="icon ion-chevron-right icon-accessory"></i>
            <ion-option-button class="button-assertive" ng-click="remove(chat)">      Delete        

When i click list time , it will go to map with latitude and longitude stored in local database.I want to set longitude, latitude dynamically from local sqlite database to new google.maps.LatLng(23.730182 , 90.408583); .

Here is map controller
//Being map controller
angular.module(‘starter.directives’, [])

    .directive('map', function() {

var myCenter=new google.maps.LatLng(23.730182 , 90.408583);

      return {

        restrict: 'E',

        scope: {

          onCreate: '&'

        link: function ($scope, $element, $attr) {

          function initialize() {

            var mapOptions = {



              mapTypeId: google.maps.MapTypeId.ROADMAP


    		var map = new google.maps.Map($element[0],  mapOptions);
	 var marker = new google.maps.Marker({

          position: myCenter,

          map: map,

          title: 'ERA InfoTech Limited'


            google.maps.event.addDomListener(marker,$element[0], 'mousedown', function (e) {


              return false;


    		   $scope.onCreate({map: map});

          if (document.readyState === "complete") {


          } else {

            google.maps.event.addDomListener(window, 'load', initialize);




//End map controller

I have populated list from sqlite.
longitude: res.rows.item(i).longitude,
latitude: res.rows.item(i).latitude,
are latitude and logitude value.
