NgTagsInput in ng-repeat

[mpushki]

my html:

<div class="form-group" ng-repeat="(matchIdx, match) in matches track by matchIdx">
    <div class="form-group">
        <div class="col-sm-6">
            <input type="number" class="form-control"  ng-model="data[matchIdx].number">
        </div>
    </div>
    <div class="form-group">
        <div class="col-sm-6">
                <tags-input class="bootstrap"
                placeholder=" "
                key-property="id"
                display-property="label"
                ng-model="data[matchIdx].tags">
                <auto-complete source="loadTags($query)"
                     min-length="1"
                     max-results="10"></auto-complete>
                </tags-input>
        </div>
    </div>

Matches list contains 30 items and more. The number of watches in this case is more than 10 000. I tried another lib (ui-select), the result is even worse.

Can anybody help? can I use another library (more fast)? Or how can I organize my code differently to have something similar to dynamically adding tags for each row on gn-repeat?
