Am not sure if that is possible. 
One quick hack.. we could achieve this with an extra boolean field (say B). 

You could have 2 buttons(say 1&2) in the view pointing to the same function but with different string value in xml. Once clicked, change that boolean field to True. 

so in view, you could write like 
1--> visible when B is False
2--> visible when B is True

Until you find proper  solution, you could use like this.
