I need set valuse from my table, for use this in my template. 

code:

js:

console.log('Hi im work')
odoo.define('sale.ch15_r01_drag', function (require) {
    'use strict';
    var core = require('web.core');
    var QWeb = core.qweb;
    var relational_fields = require('web.relational_fields');
    var registry = require('web.field_registry');
    var rpc = require('web.rpc');
    // var model = new instance.web.Model("oepetstore.message_of_the_day");
    var ContactDragWidget = relational_fields.FieldMany2Many.extend({
        template: "Field.Drag.template",
        events: {
        'click .o_attach': '_onAttach',
        'click .o_attachment_delete': '_onDelete',
        'change .o_input_file': '_onFileChanged',
    },
        fieldsToFetch: {
        display_name: {id: 'integer'},
        mimetype: {type: 'char'},
    },

        willStart: function() {
            return Promise.all([
                this._super.apply(this, arguments),
                this._getHtml()
            ]);
        },

qweb:
