[REACT] addPartner first time is OK, but second time it says partner.on is not a function

[jiuxiang meng]

when I use addPartner in the first time it is OK, but when I use it in the second time, it says

TypeError: partner.on is not a function
me.getConfig('viewPreset');
partner.on({
   presetchange:'onPartnerPresetChange',
   thisObj:me
})

Best regards,
