TypeError: Object of type 'function' is not JSON serializable

函数类型不是JSON 序列化需求的类型，这个有大神可以帮忙看看吗？python3用到bokeh制表的library

def selectAllCallback(epnoPlotSource=epnoPlot, toPlotSource=TOPlot, smtToPlotSource=smtTOPlot,
    phasePlotSource=phasePlot, smtPhasePlotSource=smtPhasePlot, ampRatioPlotSource=ampRatioPlot,
    ampPlotSource=ampPlot, peakPlotSource=peakPlot, absoluteAmpPlotSource=absoluteAmpPlot):

rxtxSelect.js_on_change('value', CustomJS(args=dict(source=commonCallback),code=""))
lnCellSelect.js_on_change('value', CustomJS(args=dict(source=commonCallback),code=""))
selectAllButton.js_on_click(CustomJS(args=dict(source=selectAllCallback),code=""))
clearAllButton.js_on_click(CustomJS(args=dict(source=clearAllCallback),code=""))

c = column(epnoPlot,TOPlot,smtTOPlot,phasePlot,smtPhasePlot,ampRatioPlot,ampPlot,peakPlot,absoluteAmpPlot)
l = layout([[rxtxSelect, lnCellSelect], [selectAllButton, clearAllButton],c])
save(l)
