Reg. WiX Data API - .update() Method | Velo

Hi Eitan,

I am trying to follow this video of yours to achieve something similar, however the code would just not run on hitting that SUBMIT button.

I have checked the complete code and I couldn't find any error of any sort. What am I missing here?

The Code:

//--------------------------------------
// Code to UPDATE dataset entries
import wixData from 'wix-data';

$w.onReady(function () {
    const myCollection = "MS";
        let idToUpdate = "";

	// Calling & Displaying all data fields
    const selectItemForUpdate = (itemData) => {
        $w("#input15").value = itemData.personName;
        $w("#dropdown1").value = itemData.designation;
		$w("#input16").value = itemData.personPhone01;
		$w("#input18").value = itemData.personalWhatsApp01;
		$w("#input17").value = itemData.personalEmailText;
		$w("#dropdown2").value = itemData.gender;
		$w("#input19").value = itemData.website01;

		$w("#input26").value = itemData.description;
		
        idToUpdate = itemData._id;
        }

	// Declaring Item to update function
    const updateItem = () => {
    //	let toUpdate = {
	// 	"_id": idToUpdate,
    //  "personName": $w("#input15").value,
	//	"designation": $w("#dropdown1").value,
    //	"personPhone01": $w("#input16").value,
	//	"personalWhatsApp01": $w("#input18").value,
	//	"personalEmailText": $w("#input17").value,
    //	"gender": $w("#dropdown2").value,
	//	"website01": $w("#input19").value,
	//	};

        wixData.get(myCollection, idToUpdate)
        .then((item)=>{
			let toUpdate = item;
			toUpdate.personName = $w("#input15").value;
			toUpdate.designation = $w("#dropdown1").value;
			toUpdate.personPhone01 = $w("#input16").value;
			toUpdate.personalWhatsApp01 = $w("#input18").value;
			toUpdate.personalEmailText = $w("#input17").value;
			toUpdate.gender = $w("#dropdown2").value;
			toUpdate.website01 = $w("#input19").value;
		
			toUpdate.description = $w("#input26").value;
	
		wixData.update(myCollection, toUpdate)
        	.then((results) => {
        		console.log(results); //see item below
      		})
	        .catch((err) => {
    		    console.log(err);
        	});
		})	
	}

// Populating fields with a button click (unnecessary but following the code)
$w("#button443").onClick(($item, itemData, index)=>{
	$item("item").onClick()
	})

// Submitting the values to dataset
        $w("#button20").onClick(updateItem);        
		//...


		/*  item is:
        *
        *  {
        *    "_id":          "00001",
        *    "_owner":       "ffdkj9c2-df8g-f9ke-lk98-4kjhfr89keedb",
        *    "_createdDate": "2017-05-24T12:33:18.938Z",
        *    "_updatedDate": "2017-05-24T12:33:18.938Z",
        *    "title":        "Mr.",
        *    "first_name":   "John",
        *    "last_name":    "Doe"
        *  }
        *

Appreciate any help. Thanks in advance.
