For example:
<div data-binding-repeat="{{queryTest.data.queryTest}}" data-binding-id="repeatQuery">
<input name="Field[{{id}}]" type="text" value="{{formula}}" />
</div>
I have a table with 3 rows and in the column "formula" I have the values:
For Field with ID 1: 1
For Field with ID 2: 3
For Field with ID 3: ($FORM.Field[1].toNumber()+$FORM.Field[2].toNumber())
but after loading the repeat region I see only text of my formula but not calculated...

Hello,
Is the Field with ID 3: ($FORM.Field[1].toNumber()+$FORM.Field[2].toNumber()) inside the repeat region?

Yes, but the Field with ID 3 has also {{formula}} as data-binding-value. In database for Field with ID 3 I have the value ($FORM.Field[1].toNumber()+$FORM.Field[2].toNumber())... How can I re-render dmxDataBinding?

So where exactly the ID 3 {{formula}} goes?

In the database I have the following data:
prnt.sc/bv9ng4

I am afraid what you are trying to achieve is not possible. You can use the sum filter, from the data bindings formatter and sum the values of the repeat region outside of it.
