The clash between Angular's ng-if directive and Bootstrap's popover feature causing unexpected

<div class="form-group" ng-if="firstname">
    <label>First Name</label>
    <input readonly type="text" class="form-control" id="first_name" ng-model="firstname" placeholder="First Name">
    <a href="" data-toggle="popover" data-placement="bottom" data-trigger="focus" data-content="User Name" class="glyphicon glyphicon-info-sign infottp"></a>
</div>

I have implemented the provided code above in my project. I am currently facing an issue where the popover is not functioning properly when using the ng-if condition to show or hide elements, instead of using the ng-show and ng-hide directives. However, if I switch to using the ng-hide directive or remove the ng-if condition altogether, the popover works perfectly fine. I would like to understand the reason behind this behavior and find a solution to make the popover work with the ng-if condition.
