(fixes: #31) setOnClickListener getting callback twice

[amankumar367]

To Verify

Put the below code in MainActivity.kt of demo-programmatically-add-buttons module

val btn2 = ThemedButton(buttonGroup.context)
btn2.text = "Button 2"
btn2.isEnabled = false
buttonGroup.addView(btn2, ViewGroup.LayoutParams(WRAP_CONTENT, MATCH_PARENT))


buttonGroup.buttons.forEach { button ->
      if (button.isEnabled.not()) {
            button.setOnClickListener { 
                    Toast.makeText(this, "${button.text} clicked", Toast.LENGTH_SHORT).show()
            }
      }
}

also don't forget to changes in build.gradle file

// implementation 'nl.bryanderidder:themed-toggle-button-group:1.3.4'
implementation(project(":library"))
implementation 'com.google.android.flexbox:flexbox:3.0.0'

btn.performClick() should call only once when action = isActionUp
