Handler this.handleColumnSwitch doesn't work for MIGX TVs in MODX 3

[halftrainedharry]

In MODX 3, a "click" event on the MIGX-TV grid doesn't seem to get handled by the custom listener (onClickGrid),

MIGX/core/components/migx/templates/mgr/grids/migx.grid.tpl

Line 711 in 352a909

,onClickGrid: function(e){

because a click handler was added for the "Actions-Column":

A possible solution to fix this is described in this forum post:
