Ace editor autocomplete uploads extra-records - angularjs

Question

I added ui-ace editor to the my application with angular. Instead of requesting words every time, I get a json 1 time, during application initiation.
Example of json-file:
[
{
"Word": "Do {int} + {int}",
"Meta": "Implemented"
},
{
"Word": "Line3",
"Meta": "Not-implemented"
},
{
"Word": "Line2",
"Meta": "Not-implemented"
},
{
"Word": "Line4",
"Meta": "Not-implemented"
},
{
"Word": "444",
"Meta": "Not-implemented"
},
{
"Word": "E1",
"Meta": "Not-implemented"
},
{
"Word": "E2",
"Meta": "Not-implemented"
},
{
"Word": "E1Try",
"Meta": "Not-implemented"
},
{
"Word": "E3",
"Meta": "Not-implemented"
},
{
"Word": "E4444",
"Meta": "Not-implemented"
}
]
The issue is that some of words are listed in autocomplete more than ones, take a look on a screenshot: http://take.ms/N8BFZ .
Here's how I load ace-editor, where ctrl.listStepLines is an object which contains json-response from API:
$scope.aceLoaded = function(_editor){
// Editor part
var _session = _editor.getSession();
var _renderer = _editor.renderer;
_editor.$blockScrolling = Infinity;
_editor.setOptions({
minLines: 10,
maxLines: 40,
wrap: true,
firstLineNumber: 1,
enableBasicAutocompletion: true,
enableSnippets: true,
enableLiveAutocompletion: true
})
var langTools = ace.require("ace/ext/language_tools");
var rhymeCompleter = {
getCompletions: function (editor, session, pos, prefix, callback) {
if (prefix.length === 0) { callback(null, []); return }
callback(null, ctrl.listStepLines.map(function (ea) {
return { name: ea.Word, value: ea.Word, meta: ea.Meta }
}));
}
}
langTools.addCompleter(rhymeCompleter);
};

The issue was that angularjs loaded my function a lot of times and ace editor had 14 similar completers. I refactored my code and create a separate function for completer adding which is called only one time.
ctrl.addAutoCompleter();
function init() {
ctrl.addAutoCompleter = function () {
var langTools = ace.require("ace/ext/language_tools");
var stepLineCompleter = {
getCompletions: function (_editor, session, pos, prefix, callback) {
if (prefix.length === 0) { callback(null, []); return }
callback(null, ctrl.listStepLines.map(function (ea) {
return { name: ea.Word, value: ea.Word, meta: ea.Meta }
}));
}
}
langTools.addCompleter(stepLineCompleter);
}
};
