Channel Entry Form: Grid fields (sort / delete)

I am using a grid field on a channel entry form. When I am editing the entry on the front end every time I submit the form a new blank row is created in my grid field.

The sorting and deleting also does not work in my form.

errors: Uncaught TypeError: $(…).sortable is not a function at HTMLTableElement.<a> (http://ldomain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…rid,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:708:77) at Function.each (http://domain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…id,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:2:12099) at Z.fn.init.each (http://v.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…id,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:2:10073) at Z.fn.init.$.fn.eeTableReorder (http://domain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…rid,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:708:45) at i.Publish._bindSortable (http://domain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…rid,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:814:47) at i.Publish.init (http://domain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…id,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:805:382) at i.Publish (http://domain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…id,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:805:309) at Object.EE.grid (http://domain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…id,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:1097:30) at HTMLDocument.<a> (http://domain.ca/index.php/profile/update/sample:828:5) at c (http://domain.ca/index.php?ACT=4&ui=core,widget,mouse,position,drag…rid,underscore,cp/date_picker,cp/date&v=1479305408&include_jquery=y:3:3465)
