button ".glyphicon-remove" doesn't work, I use bootstrap 3.

The button ".glyphicon-calendar" is ok, but the button ".glyphicon-remove" doesn't work.
The code at line 65 in bootstrap-datetimepicker.js can't find the object.

Line 65:
"this.componentReset = this.element.is('.date') ? ( this.bootcssVer == 3 ? this.element.find('.input-group-addon .glyphicon-remove .fa-times').parent() : this.element.find('.add-on .icon-remove .fa-times').parent()) : false;"

so I modify it like this:
"this.componentReset = this.element.is('.date') ? ( this.bootcssVer == 3 ? this.element.find('.input-group-addon .glyphicon-remove, .input-group-addon .glyphicon-remove .fa-times').parent() : this.element.find('.add-on .icon-remove .fa-times').parent()) : false;"
After I modify it, the object can be find,and the button ".glyphicon-remove" is work.

My bootstrap version: v3.2.0.
