Date Picker value not sending on Apply

I think this is a bug, I have a datepicker set to run a server action database update on Apply but the date value does not show up

<dmx-serverconnect id="sc_date_edit" url="api/image-manager/photograph-date-edit" noload dmx-on:success="scimagelist.load({})"></dmx-serverconnect>

<input type="text" class="form-control" placeholder="Please Choose Date" dmx-bind:value="mil_photographed_date" is="dmx-date-picker" timepicker="" use24hours="true" id="phoDate" name="phoDate" dmx-on:apply="sc_date_edit.load({what_image_id: mil_id, what_date: value})">

EDIT: Just out of interest this does not work with dmx-on:changed either, however it does work with dmx-on:updated
