Unable to perform data binding inside stepper component
I have 2 input fields called Course name(Autocomplete component) and Price(input component):
On selecting particular Course name,the price was displaying according to the Course name like this:
Now, I have placed these two input fields (i,e course name and price) inside stepper component.Then data binding is not happening(i,e on selecting course name i am unable to display the price ).

There are two issues:
You should use the
nameattribute if you're using[(ngModel)]. But you haven't used it.There's an issue with this implementation:
this.offeringControl.valueChanges.subscribe((d) => {
console.log('Changed');
console.log('d: ', d);
if (d === 'CCNA Training') {
this.price = this.matPrice;
} else if (d === 'Java Coaching') {
this.price = this.phyPrice;
} else if (d === 'PHP Training') {
this.price = this.chemPrice;
}
});
Here, the strings CCNA Training, Java Coaching, and PHP Training should be, Maths, Physics, and chemistry.
As your AutoComplete only has Maths, Physics, and chemistry.
Here's a fixed and Updated StackBlitz for your ref.
