关于setData赋值给data，wxml绑定的值没有发生改变？Regarding the assignment of setData to data, the value bound to wxml has not changed?

Send a request to the back end and assign a value through SetData, console.log () the value in data changes, the data in appdata changes, and the value of wxml binding cannot be changed. Manually changing the wxml value page has not changed.
