How solve problem with Binding?

Hi

I have many problems with binding!

I have InputField1 (type string) bindet to VAR1 (from Context -> Node -> Attribute)

I have TextView1 bindet to VAR1

When I write to InputField1 (bindet to VAR1) and press Enter TextView1 (bindet to VAR1) is not changed

When I have InputFiled2 (type D) bindet to VAR2 (from Context -> Node -> Attribute)

And TextView2 bindet to VAR2 (from Context -> Node -> Attribute)

When I select value through search help in InputFiled2 value in TextView2 is not changed!

Where is a problem?

Thank you
