The possible solution which I found is to add below line of code inside triggerDropdownAdvanced finction,

element.trigger.exec(searchable);

see below code snippet

else if(typeof(element.trigger) === 'object'){
// I need to get the index of the last match
var searchable = text.substr(0, position),
match, found = false, lastPosition = 0;
while ((match = element.trigger.exec(searchable)) !== null){
if(match.index === lastPosition){
break;
}
lastPosition = match.index;
if(match.index + match[0].length === position){
found = true;
element.trigger.exec(searchable);
break;
}
}
if(found){
element.list(match, function(data){
$scope.dropdown.content = data.map(function(el){
el.display = $sce.trustAsHtml(el.display);
return el;
});
$scope.dropdown.customSelect = element.onSelect;
$scope.dropdown.mode = element.mode || 'append';
$scope.dropdown.match = match[1];
$scope.dropdown.showFilter = element.filter || false;
});
}
}
