Angular modal service closing issue - angularjs

Question

I am using angular modal service to show incoming call popup.
Everything seems to work but in particular case the popup closes leaving behind grey overlay blocking the whole UI.
Popup closes perfectly when i manually click reject and close button provided in popup but gives unusual behaviour when i use timeout to close the popup whithout doing any operation on it.
For reference i am giving my whole code.
----------------------------modal popup UI code---------------------------
<div class="modal fade">
<div class="modal-dialog modal-lg modal-dialog-custom">
<div class="modal-content modal-content-dialog">
<div class="modal-header">
<audio class="incoming-videoconference-audio" autoplay loop>
<source src="../images/dataCallIncoming.mp3" type="audio/mpeg">
</audio>
<button type="button" class="close" ng-click="vm.hangUp()" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Incoming Call</h4>
</div>
<img class="incoming-nowConf-logo" src="../images/new_nowconfer_e.png" />
<div id="state" class="grid_4 alpha">
<div class="gps_ring"></div>
</div>
<div class="modal-body modal-body-custom">
<div style="text-overflow:ellipsis;overflow:hidden;" class="call-from">
{{vm.confName}}
</div>
<div class="call-control">
<button type="button"class="btn-sm btn-sm-gray cancel-btn" ng-click="vm.hangUp()" data-dismiss="modal">Reject</button>

-------------------------modal popup controller------------------------------

var vm = this;
vm.connecting = false;
vm.from = from;
vm.confName = confName;
vm.dismissModal = function(result) {
plivoclient.conn.reject();
console.log('vm.dismissModal::'+result);
close(result, 200); // close, but give 200ms for bootstrap to animate
};
activate();
function activate(){
$timeout(function(){
vm.dismissModal('cancel');
},25000);
}
vm.accept = function() {
plivoclient.conn.answer();
vm.connecting = true;
console.log("incoming call accept............");

},300);
};
vm.hangUp = function() {
plivoclient.conn.reject();
vm.dismissModal('reject');
console.log("incoming call hangedup............");
};
}
}());

I have spent hours on internet to figure out why this is happening but failed to solve it,i feel when any click event happens then it works fine but fails to close properly when on operation is performed.Please help!!
thanks in advance

Answer 1

I had the same issue and it was due to a comment at the top of my HTML file. When I removed the comment, it worked fine.
I didn't get the reason of this bug though.
hope you have the same case.
