How bind select options in the HTML with two pre-defined values to insert data in mongodb

I create an event creator in my admin dashboard, and everything is working ok, but now i need insert a new field:

infoType: Object

In my HTML event creator, i have this selection:

<label for="infoType">Information Type:</label>
<select id="infoType" name="infoType">
 <option>Normal</option>
 <option>Special</option>
</select>

With a post to /event/create

When this event arrive in my controller, i need save all the form inputs in my database, and is fine, this part is 100% working.

But, before make the save, i am using this code to bind the select option with the real value of the field infoType in the database:

event.pre('save', function(next) {
 if (this.infoType === 'Normal') {
   this.infoType = [
    ['Normal text.'],
    ['Normal text continuation.']
    ['Normal text continuation']
   ]
 } else if (this.infoType === 'Special') {
   this.infoType = [
    ['Special text.'],
    ['Special text continuation.'],
    ['Special text continuation.']
   ]
 }
});

I want know if this is right, is working, but for me looks wrong.

I CANT change the way that i am using to insert text, i need separate the texts in arrays, because i am using a for loop to show this texts in an unordered list, and i don't know other way to make the code looks like this:

<ul>
  <li>ARRAY 1</li>
  <li>ARRAY 2</li>
  <li>ARRAY 3</li>
</ul>
