uis-open-close not working for version 0.19.8

[ankurraiyani]

Bug description:

We want to use uis-open-close directive but it's not working as expected.
Below is the code snippets,

<ui-select my-ui-select ng-model="selected.value2">
    <ui-select-match>
        <span ng-bind="$select.selected.name"></span>
    </ui-select-match>
    <ui-select-choices repeat="item in myModalCtrl.itemArray">
        <span ng-bind="item.name"></span>
    </ui-select-choices>
    <uis-open-close uis-open-close="openClose(isOpen)"/>
</ui-select>
