Datepicker options not working

I spent hours on this and it’s still not working…
I tried using tsega:bootstrap3-datetimepicker, followed the exact instructions:

<template name="ABC">
...
  <div class="input-group datetimepicker">
    <span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
    <input class="set-due-date form-control" type="text"/>
  </div>
...
</template>

Template.ABC.onRendered(function() {
    this.$('.datetimepicker').datetimepicker();
});

and it doesn’t work. I get a blank text input

I tried rajit:bootstrap3-datepicker got it to the point it does show up but I cannot get any of the options to work:

In ABC template (html):

div id="arrival" class="form-group">
     <label class="col-sm-3 control-label">Choose Date</label>
    <div class="col-sm-7" >
	<input type="text" class="form-control" id="date1"/>
    </div>
</div>

In ABC (js):

Template.ABC.onRendered(function() {
    $('#date1').datepicker({startDate: "01/01/2017"})
})

Template.ABC.events ({           
  'focus #date1': function () {
    $('#date1').datepicker('show')

  }
});

Without the ‘show’, I get no date at all.
Any of the options like format, etc not working (if I use format as attribute in the html it does change the format).
What am I doing wrong here?

I just created a very small reproduction and it totally works. You just need to click on the little glyph or add this event handler

Template.tempName.events({
    'focus input'(event, instance){
        var data = instance.$('.datetimepicker').data();
        data.DateTimePicker.show();
    }
});
