  view.$el.find('input[type=text]').selectize({
    valueField: 'code',
    labelField: 'code',
    searchField: ['code', 'description', 'title'],
    delimiter: ',',
    create: true,
    createFilter: /^[0-9]+$/,
    render: {
      option: function(item, escape) {
        if (item.title) {
          return '<div>' + escape(item.title) + ' (' + item.code + ')' + '</div>';  
        } else {
          return item.code;
        }
      }
    },
    load: function(query, callback) {
      if (!query.length) return callback();
      $.ajax({

            terms: query
        },
        error: function() {
          callback();

        success: function(res) {
          callback(res);
        }
