How to set global configuration of Gillardo/bootstrap-ui-datetime-picker in angularjs

Question

I am using Gillardo bootstrap-ui-datetime-picker in my application and i wanted to override some default setting(wanted to remove buttonBar).For that i have used the following code which does not solve my problem (code get from library documentation uiDatetimePickerConfig Documentation). I have also searched but didn't find any help.

Note:Library is working fine only i wanted to remove buttonBar

Any suggestion.

Here html where shown datetimepicker

<p class="input-group">
                          <input type="text" class="form-control ng-valid ng-isolate-scope ng-valid-datetime ng-dirty ng-touched ng-not-empty"
                                               datetime-picker="HH:mm" ng-model="range.endTime"
                                               is-open="range.dEndTime" enable-date="false" 
                                               readonly>
                                        <span class="input-group-btn">
                                            <button type="button" class="btn btn-default" ng-click="controller.openCalendar($event,range,2)"><i class="fa fa-clock-o"></i></button>
                                        </span>

After long time spend just found a way but this is not a globall . just added this line button-bar="{{false}}" in input element.

Code

<p class="input-group">
                                        <input type="text" class="form-control ng-valid ng-isolate-scope ng-valid-datetime ng-dirty ng-touched ng-not-empty"
                                               datetime-picker="HH:mm" ng-model="range.endTime"
                                               is-open="range.dEndTime" enable-date="false" 
                                               button-bar="{{false}}" readonly>
                                        <span class="input-group-btn">
                                            <button type="button" class="btn btn-default" ng-click="controller.openCalendar($event,range,2)"><i class="fa fa-clock-o"></i></button>
                                        </span>

                                    </p>
