var contact = {
    view:"window", modal:true, id:"contact-win", left:320, top:290, width:780, css:"bradius",
    head:{
        view:"toolbar", margin:-4, cols:[

        ], onClick: {
                "fa-trash": function(e, id) {
                    $$('plda_contact').remove(id.row);
                }
            }},
            {
            view:"form", id:"contact_form",
            elements:[
                {view:"layout", id:'contact_layout', margin: 4, cols:[
                  {view:"text",  label:"e-mail", name:"DDCHI", id:"DDCHI", loaded:0, contactneeded: 1, labelWidth: 60},

                   }
                    }
                ]}
            ],
            rules:{"DDCHI": webix.rules.isEmail}
        }
        ]
    }
};
    webix.ready(function () {
      webix.ui(contact);
      $$('plda_contact').parse(data);
      $$('contact-win').show();
    });

The onClick fires earlier than selection/itemClick handlers, so the script will throw an error, as it is unable to work with a non-existing row.
To avoid any issues, prevent the further processing by returning false:

onClick: {
   "fa-trash": function(e, id) {
       $$('plda_contact').remove(id.row);
       return false;
   }
}
