Added a config option that will enable this. To get the behavior that you want, set

require('aerial').setup({
  update_events = 'TextChanged,TextChangedI'
})

The default is TextChanged,InsertLeave

Thanks, suggestion: allow update_events to be a table

-- config
require('aerial').setup({
  update_events = {'TextChanged', 'TextChangedI'}
})

-- using config
table.concat(config.update_events, ',')
