Kenmore toaster oven handle fell off

The handle of my Kenmore toaster oven fell off. It was glued on with some sort of clear, light-tan colored rubbery substance, very elastic. I tried to reattach it with a two-tube epoxy type glue, which adhered to the metal brackets but not to the plastic handle. The brackets don't fit into anything, and don't even line up very well with the corresponding plastic surfaces on the handle. Very poor design, no mechanical strength at all. I need to know what sort of adhesive will re-bond the metal bracket to the plastic handle. Thank you.
