Not able to fetch the mention data on submit !!

[akum001]

#First i am calling getMentions

$('textarea.mention').mentionsInput('getMentions', function(data) {
var temp = JSON.stringify(data);
console.log(temp)
});

#Then it's coming here!

getMentions : function (callback) {
debugger;
if (!_.isFunction(callback)) {
return;
}
callback.call(this, mentionsCollection);
}

#Then here!

return this.each(function () {
var instance = $.data(this, 'mentionsInput') || $.data(this, 'mentionsInput', new MentionsInput(settings));

        if (_.isFunction(instance[method])) {
            return instance[method].apply(this, Array.prototype.slice.call(outerArguments, 1));
        } else if (typeof method === 'object' || !method) {
            return instance.init.call(this, this);
        } else {
            $.error('Method ' + method + ' does not exist');
        }
    });

It should take only current textarea object but don't understand from where it's fetching these many textareas.

it should return just first obj mentionsCollection but it returning so many empty arrays after that.
