Preheat a grill to medium high. Combine the butter, garlic, lime juice, cilantro, chile paste and cumin in a bowl. Add salt and pepper; mix well.
Grill the corn, turning, until nicely charred, 10 to 15 minutes. Serve with a spoonful of the flavored butter on top. Sprinkle with more cilantro and cotija cheese.
