Why the metapost not updated the value of text variables that are generated
inside luacode environment?

In the code below, If I have \startitemize[columns,two] then metapost draw:

1. \Bolha[size=6cm]{text1}{text2}{text3},
2. and four  \Bolha[size=4cm]{text1}{text2}{text3}, but text1, text2 and
text3 is not updated in every call;

Use useMPgraphic instead of uniqueMPgraphic.

uniqueMPgraphic recomputes the graphic only when the dimensions of figure has changed; otherwise, it reuses the previously drawn graphic. This behavior was useful for drawing page-backgrounds etc in MkII where calling metapost was slow.
