displayOnFocus not working

[JoelKap]

Hi, It seems like [taDisplayOnFocus] doesn't seem to work or perhaps, am not using it correctly.
<input type="text" placeholder="search channel"
[value]="query"
ngxTypeahead
class="col-sm-12 form-control"
[taList]="channels"
[taListItemLabel]="'codeName'"
[taDisplayOnFocus]="displayOnFocus"
(taSelected)="handleResultSelected($event)">

Same for me: With taDisplayOnFocus I get no ta selector, only after the first character get's entered it is filled.
From that moment on, that single field works as expected.
