Display only the first string word (Jquery)

I would like this return to return the entire string that contains the data.notes variable. For now, he only returns the first word. As soon as the first empty space is reached. I use the Bootsrap 3 tooltip on the data tables, although I think it does not matter.
Example: data.notas = "hello how are you";

result: hello

return"+ data.name +"";
