Show loading option in angularjs while fetching content using $http -

i creating directive have reusable way show option labeled 'loading...' in select tag. problematic comes because i'd notified specified connection (as shown in fiddle) , because i'd directive know nothing model ($scope).

the fiddle @ http://jsfiddle.net/5uhbn/8/ code, i'll show i'm trying @ moment. following handler called @ start of connection:

var startrequesthandler = function() {     ngmodelctrl.$setviewvalue(obj);     selectctrl.addoption(msg);     /**      * above i'd want angular adding element combo.      **/     console.log('started endrequesthandler'); }; 

the next handler called when connection done , resets value:

var endrequesthandler = function() {     selectctrl.removeoption(msg);     ngmodelctrl.$setviewvalue(null);     /**     * above i'd want angular removing element combo.     **/     console.log('ended endrequesthandler'); }; 

thank you!
