Expanding paremeters

[cshjsc]

Hi, I\m trying to get to work the expanding of arguments when selecting a method from the suggestions, what happens its just the name of the method gets expanded but not the arguments.
what happens:
type x.some -> x.someMethod
what should happen:
type x.some -> x.someMethod(a,b,c);

It doesn't work for java but it works for rust.
I don't think it's a problem with the lsp because it works with another completion engine(lsp_compl).
I also have activated Luasnips
