You should try to fix this by up/downgrading your theme/plugin. But if you, like me, can't solve it this way and just need to do a quick hack to get past this particular problem, the following worked for me.

Edit the following two files:

wp-content\plugins\js_composer\assets\js\frontend_editor\frontend_editor.js
wp-content\plugins\js_composer\assets\js\frontend_editor\custom_views.js

Change a single line in each of them, adding (). Change:

this.$controls = $( _.template( template, data, vc.template_options ).trim() ).addClass( 'vc_controls' );

to:

this.$controls = $( _.template( template, data, vc.template_options )().trim() ).addClass( 'vc_controls' );
