Auto-Fill Angular Website Form

[Ani85]

We are having a customized website that is in Angular form and i am trying autofill it using Excel VBA for bulk creation. My problem is that i am able to auto fill all the fields of the form but they are not getting recognized and the create button stays greyed out. Only if i click using mouse and edit using keyboard it gets recognized and the create button gets highlighted.
Please help me here in getting the inputs recognized.

The script/query i have used is below:
Sub FillInternetForm()

Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")

IE.navigate "https://{angularwebsiteform}.com/wizard"
IE.Visible = True

While IE.Busy

DoEvents

IE.document.getElementById("mat-input-1").Value = ThisWorkbook.Sheets("Sheet1").Range("b1").Value
IE.document.getElementById("mat-input-2").Value = ThisWorkbook.Sheets("sheet1").Range("b2").Value
IE.document.getElementById("mat-input-3").Value = ThisWorkbook.Sheets("sheet1").Range("b3").Value

IE.document.getElementById("mat-input-11").Value = ThisWorkbook.Sheets("sheet1").Range("b11").Value
IE.document.getElementById("create").Click
