How to set value for Input Box

There is an external system API that would send the result in text format.

I am able to show the result of the text format in  a toast message in a function.

sap.m.MessageToast.show(APIResult.textformat);

I now need to assign the APIResult.textformat value to an Input box in the UI after i get the result from the esternal server. How can this be achievable.

Below is the code i use.

What is that i am missing in the code to not able to set the toast value in the input box

Thanks
